UN Investigators Deploy to Lebanon: War Crimes Probe Exposes 3,600+ Death Toll
United Nations Office of Human Rights is set to send its investigators to Lebanon in the coming week, signaling an important development in terms of global initiatives to investigate the possibility of war crimes in the war that lasted for 100 days and took the lives of more than 3,000 individuals while displacing over one million civilians. The announcement regarding the mission was made by the UN High Commissioner for Human Rights Volker Türk on Wednesday, June 10, as the mission was to investigate any violations of international law committed by the parties involved.
The current investigation is the most significant attempt by the UN to address the conflict between Lebanon and Israel, which has now reached an all-time low with at least 3,042 dead, among them 211 children and 292 women, while over a million Lebanese people have been displaced from their homes. With talks failing to bear fruit and cease-fires being ineffective and as tensions escalate between the sides, the UN’s move can be seen as the increasing realization of the international community that the Lebanon-Israel crisis is fast becoming a “crucial flashpoint” of the escalating Middle East war.
UN Investigation Mission: Scope, Timing and Legal Authority
The UN Human Rights Office’s investigation team is scheduled to travel to Lebanon within the coming week based on the statement by Türk. This team is made up of internationally recognized experts on human rights who have been mandated to investigate any violation of human rights that occurs throughout Lebanon. The period to be investigated starts from March 2, 2026, up to date and entails bombings of civilians’ housing, assaults on hospitals, forced displacement of citizens, and random rocket attacks on populated places.
Volker Türk emphasized the investigation’s impartial nature, stating that UN High Commissioner Volker Türk calls for
“prompt, thorough, independent, and impartial investigations into all incidents involving allegations of violations of international humanitarian law.”
The mandate encompasses investigations into any breaches carried out by both Israeli forces executing air raids in Lebanon and Hezbollah rebels executing unguided rocket attacks at Israel, and therefore is an all-encompassing review of possible violations committed by everyone involved and not directed at any particular side. The investigation will establish certain trends that constitute serious violations of international humanitarian law, which include: Attacks on civilians; Attacks on medical personnel and facilities; Forced displacement involving over one million people; Failure to distinguish military objectives from civilian objects.
UN spokesperson Nahneen-Kheet explained that
“These actions may represent serious violations of international humanitarian law,”
particularly regarding Israeli bombardments that have struck residential buildings containing entire families.
Death Toll Surpasses 3,000: Civilian Casualties Define Conflict Horror
There has been a terrible loss of life resulting from the war between Israel and Lebanon, where according to a report from Lebanon’s ministry of health, there have been 3,042 deaths since March 2 due to Israeli attacks, where 292 women and 211 children were among the deaths recorded. The level of fatalities has become alarming to the extent that the UN High Commissioner stated,
“The scale of the killing & destruction in #Lebanon today is nothing short of horrific.”
Unfortunately, May 18, 2026, saw another dark day when the number of deaths surpassed 3,000, where at least 740 deaths were recorded following the April 17 ceasefire to show the violation of the principles of international humanitarian law despite the supposed truce period. The most affected victims have been health professionals who are estimated to be at least 116 individuals who lost their lives as a result of Israel’s military attacks.
It should be noted that the breakdown of civilian casualties showed that the majority of civilian deaths belong to children and women with 211 deaths and 292 deaths, respectively. The above-mentioned figures indicate the failure of Israel to adhere to the principles of distinction and proportionality as outlined in the international humanitarian law because the former entails a distinction between civilians and combatants while the latter emphasizes the need to conduct attacks that are proportional to the military objective.
Israeli forces have also suffered casualties, with 20 Israeli soldiers killed, 4 civilians killed, and 1 defense contractor killed in southern Lebanon since early March. Additionally, 6 UN peacekeepers stationed in southern Lebanon were killed in the conflict, representing international personnel casualties that further complicate the humanitarian situation. However, the scale of civilian deaths in Lebanon—exceeding 3,000—far surpasses Israeli casualties, highlighting the conflict’s disproportionate human cost.
Displacement Crisis: One Million Lebanese Forced from Homes
As a result of the dispute, there is currently one of the biggest displacement cases in the Middle East in history, where 1 million refugees, which represent almost a fifth of Lebanon’s population, are homeless due to the Israeli ground offensive started on March 2, 2026. As per official figures, there are 1,049,328 total registered displaced persons, out of which 132,742 are living in collective centers while others stay at unofficial places.
Around 99,000 housing units have been destroyed, with the World Bank reporting damages and losses to residential buildings at $2.8 billion. The extent of displacements is almost 18% of the total population of Lebanon, with displacement levels standing at almost 1 out of 5 being displaced based on Al Jazeera’s map findings. Such an extensive level of displacement breaches humanitarian law protecting civilians from forced displacement, hence demanding humanitarian support to provide for basic necessities.
Displacements have occurred in many Lebanese provinces, with South Lebanon, North Lebanon, Mount Lebanon, Bekaa, and the suburbs of Beirut being among the most affected. Statistics from the UN between March 16-17 revealed that there had been 886 deaths during the same period, with one million people being displaced. It can therefore be seen that this conflict is characterized by the dual humanitarian crisis of both death and displacement. Displacements have led to group shelters containing more than 132,000 individuals requiring emergency services.
Israeli Military Strikes: Patterns of Potential War Crimes
These operations by the Israeli military forces have led to patterns of war, which the United Nations’ studies indicate could contravene the principles of humanitarian laws. These patterns include attacks on residential high-rise buildings within inhabited areas, destruction of buildings that leads to the death of an entire family, and lack of warning prior to any attack. The March 8, 2026 attack on the residential building in Sir el-Gharbiyeh, Nabatieh province, left at least 13 people dead including five children, where an entire family was killed in one single attack.
April 2, 2026 became witness to one of the most disastrous Israeli military actions in the conflict, where the Israeli military conducted a series of attacks on about 100 targets inside Lebanon in 10 minutes time period, leaving many civilians dead and injured. According to Heba Morayef, regional director for Amnesty International,
“just hours after the world cautiously welcomed news of [ceasefire], the Israeli military launched coordinated strikes targeting 100 Hezbollah command centers within the heart of civilian population.”
The strikes have targeted multiple Lebanese regions, including south Lebanon, north Lebanon, Mount Lebanon, Bekaa, Beirut suburbs, and central Beirut, demonstrating widespread geographic coverage of Israeli military operations. UN spokesperson Ravina Shamdasani, spokesperson for Volker Türk, emphasized
“The methods and means of warfare that are being used raises very serious concerns about whether this is compliant with international humanitarian law,”
particularly regarding indiscriminate attacks that fail to distinguish between military objectives and civilian objects.
In addition, Israeli military forces have been giving either inadequate or no warning in relation to attacks, which is not in accordance with the international humanitarian law’s requirement of proper warning before an attack. As stated in the UN report, there were instances of attacks against civilians, attacks against humanitarian and medical aid organizations, attacks against health care facilities, as well as orders of mass evacuation that would affect hundreds of thousands of people.
Hezbollah Rocket Attacks: Indiscriminate Fire Violates International Law
The militants of Hezbollah have also violated international humanitarian laws by means of launching unguided rockets that lack precision in attacking military targets. This leads to the damage inflicted on civilian infrastructures in Israel and even indiscriminate attacks on populated areas by unguided rockets. The report of the United Nations has mentioned that the violations of international humanitarian laws performed by Hezbollah could be attributed to the launch of unguided rockets on populated areas of Israel that failed to discriminate military objectives from civilians.
According to the UN report, the launch of Hezbollah rockets against Israel may be considered an offense against international humanitarian laws, owing to the fact that their unguided nature failed to inflict damage to military objectives and, therefore, resulted in civilian infrastructure destruction in Israel. Even though the number of fatalities from Israel has not surpassed those from Lebanon, the use of unguided rockets on populated areas constitutes indiscriminate violence against civilians.
The UN investigation’s scope explicitly includes violations by “all involved parties,” ensuring Hezbollah’s rocket attacks will be examined alongside Israeli airstrikes. This comprehensive approach demonstrates UN commitment to impartial documentation of violations rather than targeting specific actors, strengthening the investigation’s credibility and international legal authority. UN spokesperson Ravina Shamdasani called on
“all States and actors with influence in the region and beyond to avert further escalation and do everything they can to ensure full respect for international law.”
International Law Violations: Distinction, Proportionality and Precaution
The UN mission will focus on investigating breaches of basic rules of international humanitarian laws such as the principle of distinction, which requires armed forces to distinguish between combatants and civilians, the principle of proportionality, which entails attacks being commensurate with military objectives, and the principle of precaution, which mandates military forces to take necessary steps to prevent civilian suffering. UN spokeswoman Ravina Shamdasani noted that these breaches “raise very serious concerns about whether this is compliant with international humanitarian law.”
Attacks on civilian homes by Israel with complete families is in violation of the principle of distinction because there was no distinction made between military objectives and civilian targets. The killing of over 3,000 people also indicates that Israel might be breaching proportionality laws. Hezbollah rockets aimed at civilian areas in Israel also go against principles of distinction because they involve indiscriminate fire that cannot distinguish between military objectives and civilians.
The UN report identifies patterns including attacks on civilians, strikes on healthcare facilities, forced displacement affecting hundreds of thousands, and ineffective warnings as violations of international humanitarian law. OHCHR spokesperson Nahneen-Kheet stated
“These actions may represent serious violations of international humanitarian law,”
particularly regarding Israeli bombardments striking residential buildings. UN investigators will document these patterns comprehensively, providing evidence for potential war crimes accountability proceedings.
OHCHR Recommendations: Accountability, Ceasefire and Protection
OHCHR’s Concluding Report contains comprehensive recommendations for responding to violations. These include compliance with international humanitarian law by all sides, protection of civilians from attacks during hostilities, establishment of an effective ceasefire to halt fighting, conducting of independent investigations into all violations, accountability for those who violate laws, humanitarian assistance deliveries, and voluntary return of the displaced populations to their homes.
In terms of investigation of violations, OHCHR recommends that the government of Lebanon investigate such incidents within the jurisdiction of Lebanon, and all parties must comply with international humanitarian law. These are all important aspects in addressing the humanitarian crisis associated with the war.
