Iran’s most powerful military commander, Gen Qasem Soleimani, has been killed by a US air strike in Iraq.
The 62-year-old spearheaded Iranian military operations in the Middle East as head of Iran’s elite Quds Force.
He was killed at Baghdad airport, along with other Iran-backed militia figures, early on Friday in a strike ordered by US President Donald Trump.
Mr Trump said the general was “directly and indirectly responsible for the deaths of millions of people”.
Soleimani’s killing marks a major escalation in tensions between Washington and Tehran.
Under his leadership, Iran had bolstered Hezbollah in Lebanon and other pro-Iranian militant groups, expanded its military presence in Iraq and Syria and orchestrated Syria’s offensive against rebel groups in the country’s long civil war.
Iran’s Supreme Leader Ayatollah Ali Khamenei said “severe revenge awaits the criminals” behind the attack. He also announced three days of national mourning.
Soleimani was widely seen as the second most powerful figure in Iran, behind the Ayatollah Khamenei. The Quds Force, an elite unit of the Iranian Revolutionary Guards, reported directly to the ayatollah and Soleimani was hailed as a heroic national figure.
But the US has called the commander and the Quds Force terrorists and holds them responsible for the deaths of hundreds of US personnel.
President Trump, who was in Florida at the time of the strike, tweeted an image of the American flag shortly after the news broke.
