UN warns of mounting humanitarian toll as Israel-Iran hostilities continue

UN High Commissioner for Human Rights Volker Türk on Thursday called for “maximum restraint” and reiterated that both Israel and Iran are bound by international humanitarian law.

“The widescale, continuing attacks by Israel across Iran, and the missile and drone strikes launched in response by Iran, are inflicting severe human rights and humanitarian impacts on civilians, and risk setting the whole region ablaze,” he said in a statement.

“The only way out of this spiralling illogic of escalation is maximum restraint, full respect for international law, and return in good faith to the negotiating table,” he stressed.

Appalling collateral damage

The UN rights chief also expressed deep concern over the impact on civilians.

“It is appalling to see how civilians are treated as collateral damage in the conduct of hostilities,” he said, adding that threats and inflammatory rhetoric by senior officials on both sides suggest a “worrying intention” to inflict harm on civilians.

The airstrikes, missile and drone attacks – launched by both Israel and Iran since 13 June – have caused heavy damage to civilian infrastructure and claimed hundreds of lives.

According to Iranian authorities, at least 224 people have been killed, while human rights groups report significantly higher figures. In Israel, officials report 24 deaths and more than 840 injuries so far.

Widespread panic

Warnings from both governments have also prompted widespread panic among civilians.

Israel’s call for civilians to evacuate on Tuesday triggered panic across Tehran, resulting in heavy traffic jams on highways. Movement has reportedly been hampered across the country by fuel shortages, leading to hours-long queues at petrol stations.

Concern for refugees

The Office of the UN High Commissioner for Refugees (UNHCR) expressed grave concern over the deteriorating humanitarian situation, adding that it is monitoring reports that people are on the move within Iran and that some are leaving for neighbouring countries.

UNHCR Spokesperson Babar Baloch cautioned that the situation remained fluid and hard to verify.

“Iran has long hosted the largest Afghan refugee population in the world. Now, its own people are experiencing devastation and fear,” Mr. Baloch added.

He also emphasised the principle of non-refoulement, calling on neighbouring countries to grant protection to anyone fleeing violence, and not turn them back.

Iran hosts an estimated 3.5 million refugees and those in refugee-like situations, including some 750,000 registered Afghans and over 2.6 million undocumented individuals.

Regional worries

There is already regional fallout, with missile launches from Yemen towards Israel and the Occupied Palestinian Territory and heightened tensions reportedly involving armed groups in Iraq, according to OCHA.

“This escalation takes place as the region already grapples with mounting humanitarian needs, sharply reduced funding, and constrained operational space for humanitarian action,” the Office said in a flash update issued on Wednesday.

“De-escalation is vital to preventing further suffering of civilians and population displacements,” OCHA underscored.
