One Month of War: The Human Cost Across Every Country

A Note on These Numbers

Tracking casualties in an active, multi-theater war is inherently imprecise. Reuters published a comprehensive casualty accounting as of March 29, 2026 — drawing on figures from human rights organizations, health ministries, military statements, and international aid bodies. Reuters explicitly noted it had not independently verified all figures. Several figures also reflect different counting methodologies: some include military dead, some only civilians, and some cannot be disaggregated from available information.

All figures below are cited to their specific named sources as reported by Reuters. Where the sources' methodologies differ from each other (as in the Iran civilian count), both figures are presented.

Iran

Iran has suffered the most deaths of any country in the conflict. U.S.-based human rights group HRANA reported 3,461 people killed since the war began. Of those, HRANA said 1,551 were civilians, including at least 236 children. HRANA described its data as coming from "field reports, local contacts, medical and emergency sources, civil society networks, open-source materials and official statements," per Reuters.

A separate figure from the International Federation of Red Cross and Red Crescent Societies (IFRC), released on Friday, March 27, put the death toll in Iran at at least 1,900 people killed, with 20,000 injured in U.S.-Israeli strikes. Reuters noted it was unclear whether the IFRC figure included at least 104 people the Iranian military said were killed when a U.S. military attacked an Iranian warship off Sri Lanka on March 4.

The gap between HRANA's 3,461 and the IFRC's 1,900 reflects different counting windows, access, and methodology. HRANA counts all deaths including Iranian military and fighters; it is not clear how the IFRC is delimiting its count. Neither figure includes deaths from the ongoing conflict in Gaza or other pre-existing conflicts.

The Al Jazeera article published earlier in the conflict noted that Iran had approximately 2,000 deaths in the first three weeks. All figures show a trajectory of accelerating casualties as the conflict has continued.

Lebanon

Lebanese authorities reported 1,238 people killed in Israeli strikes since March 2, 2026, including at least 124 children, per Reuters. More than 400 Hezbollah fighters have been killed since the Lebanese armed group launched a new front with Israel on March 2, per two sources familiar with the group's count who spoke to Reuters. It was not clear whether the Lebanese authority death toll includes the Hezbollah fighter count. Eight Lebanese soldiers have been killed in Israeli strikes, with most casualties in southern Lebanon, according to the Lebanese army, per Reuters.

More than 1 million Lebanese have been displaced in the war, per AP as of March 29.

Iraq

At least 100 people have been killed in Iraq since the start of the crisis, according to Iraqi health authorities cited by Reuters. Those killed include civilians, members of the Iran-affiliated Shi'ite Popular Mobilisation Forces, U.S.-allied Kurdish Peshmerga fighters, and Iraqi army soldiers. One foreign crew member was also killed in an attack on tankers near an Iraqi port, per port security officials cited by Reuters.

Israel

Nineteen people have been killed in Israel by missiles launched from Iran and Lebanon, according to Israel's ambulance service, per Reuters. The Israeli military separately reported that five of its soldiers were killed in southern Lebanon. One Israeli farmer was also killed in a misfire by Israeli forces near the Lebanon border on March 22, per Reuters citing the Israeli military.

United States

Thirteen U.S. service members have been killed. Six were confirmed dead after a U.S. military refueling aircraft crashed over Iraq, per the U.S. military, per Reuters. Seven others were killed in action during operations against Iran. More than 300 U.S. service members have been wounded in total during Operation Epic Fury, per U.S. officials cited by Air & Space Forces Magazine.

United Arab Emirates

Ten people have been killed in Iranian attacks in the UAE, including two army soldiers, per UAE authorities cited by Reuters. The UAE Ministry of Defense separately reported (at a different point in the conflict) that it had intercepted a cumulative total of 398 ballistic missiles, 15 cruise missiles, and 1,872 drones launched by Iran toward the UAE since the war began, per Maritime Executive citing the UAE Ministry of Defense.

Qatar

Seven people were killed on March 22 in a helicopter crash in Qatar's territorial waters. Qatar's defense ministry described it as a technical malfunction during "routine duty." Of those killed, four were Qatari armed forces personnel, one was a Turkish serviceman serving in Qatar-Turkey joint forces, and two were technicians working for Turkish defense manufacturer ASELSAN, per Reuters. No further details were provided and Qatar did not describe this as a combat death.

Kuwait

Authorities reported six deaths in Kuwait, including two people killed in Iranian attacks, two interior ministry officers, and two army soldiers, per Reuters.

Saudi Arabia and Other Gulf States

Reuters' March 29 compilation did not provide a specific Saudi death toll. Earlier AP reporting and PBS NewsHour reported that more than 300 U.S. service members had been wounded in strikes including those at Prince Sultan Air Base in Saudi Arabia, which has been struck multiple times. Thirteen U.S. service members have been killed across the theater, including one previously at Prince Sultan Air Base, per Air & Space Forces Magazine.

Diplomatic Update: Pakistan Will Host US-Iran Talks

On Sunday, March 29 — Day 30 of the war — Pakistan's Foreign Minister Ishaq Dar announced that Islamabad will host talks between the United States and Iran "in the coming days," after the four-nation diplomatic summit (Pakistan, Saudi Arabia, Turkey, Egypt) concluded. Dar said "both Iran and the U.S. have expressed their confidence in Pakistan to facilitate the talks," per AP. He did not specify whether talks would be direct or indirect. The White House had not publicly confirmed the announcement as of publication. Iran's mission to the United Nations declined to comment, per AP.

The talks adjourned earlier than scheduled — initially planned to continue Monday, the diplomats departed Sunday, per AP. Iran's parliament speaker Mohammad Bagher Qalibaf separately dismissed the diplomatic track on Sunday, saying Iranian forces were "waiting for the arrival of American troops on the ground to set them on fire and punish their regional partners forever," according to Iranian state media cited by AP.

Context: Why These Numbers Are Disputed and Hard to Count

Several factors make casualty accounting in this conflict especially difficult:

Access: Iran's 30-day internet blackout (confirmed by NetBlocks) has severely limited the ability of journalists and human rights monitors to independently verify deaths inside Iran. The IFRC figure (1,900) is lower than HRANA's figure (3,461 total) partly because IFRC has limited access to conflict zones.

Military vs. civilian deaths: Different organizations count differently. HRANA specifically distinguishes 1,551 civilian deaths from 3,461 total — meaning it records approximately 1,910 combatant deaths as well. The IFRC figure of 1,900 does not clearly disaggregate civilians from combatants.

Attribution challenges: Some deaths — particularly in Iraq, where both U.S.-allied Kurdish Peshmerga and Iran-affiliated PMF fighters have been killed — are hard to attribute to a single party. The tanker attacks off the coast involve maritime casualty reporting from port authorities and navies, not standardized national health systems.

Political incentives: All governments in the conflict have incentives to either undercount (to minimize domestic political cost) or overcount (to demonstrate the enemy's brutality). Independent verification remains severely limited.
