Iran’s supreme leader has vowed “severe revenge” on those responsible for the death of top military commander Qasem Soleimani.

Soleimani was killed by an air strike at Baghdad airport early on Friday ordered by US President Donald Trump.

The 62-year-old Soleimani spearheaded Iran’s Middle East operations as head of the elite Quds Force.

Mr Trump said the US took its action to stop, not start, a war. But the killing marks a major escalation in tensions.

US officials have said 3,000 additional troops will be sent to the Middle East as a precaution.

Soleimani was widely seen as the second most powerful figure in Iran, behind Supreme Leader Ayatollah Ali Khamenei. The Quds Force, an elite unit of the Iranian Revolutionary Guard Corps (IRGC), reported directly to the ayatollah and Soleimani was hailed as a heroic national figure.

Under his 21-year leadership of the Quds Force, Iran bolstered Hezbollah and other pro-Iranian militant groups in Lebanon; expanded its military presence in Iraq and Syria; and orchestrated Syria’s offensive against rebel groups in that country’s long civil war.

US Secretary of State Mike Pompeo said the US wanted to de-escalate the situation, but that the strike was “lawful” and “saved lives”.

Later Mr Pompeo thanked Crown Prince Mohammed bin Salman for Saudi Arabia’s “steadfast support” and “for recognising aggressive threats posed by Iran’s Quds force”, the state department said.

Meanwhile, tens of thousands of Iranians have been holding rallies in Tehran and other cities, denouncing what they call US crimes.

Global oil prices rose sharply in the wake of the attack.

What have the Iranians said?

Ayatollah Khamenei said “severe revenge awaits the criminals” behind the attack. Soleimani’s death would double “resistance” against the US and Israel, he added.

He also announced three days of national mourning. The ayatollah would lead prayers at a funeral ceremony for the general in Tehran on Sunday, Iranian media quoted Soleimani’s family as saying.

Later, the Supreme National Security Council, Iran’s top security body, said the US would be held responsible for its “criminal adventurism”.

“This was the biggest US strategic blunder in the West Asia region, and America will not easily escape its consequences,” it said in a statement.

Foreign Minister Javad Zarif called the attack an “act of international terrorism”.

Soleimani’s deputy, Gen Esmail Qaani, has been appointed as his successor.

Another Middle Eastern milestone?

The Americans and their allies in Israel and the West have tracked Soleimani closely for years. It’s likely that he has been in their sights before.

The fact that this time the Americans pulled the trigger suggests that President Trump believes the reward is worth the risk, that the Iranian regime has been so weakened by isolation, economic sanctions and recent demonstrations that it will rage but not offer a serious strategic threat.

But it is not at all clear whether the assassination fits into a coherent US strategy, and such an assumption could be dangerous and wrong.

Soleimani was a colossal figure inside Iran. He was its strategic mastermind. Perhaps he left a plan of steps to take if he were killed.

This assassination at the start of a new year and a new decade might turn into another Middle Eastern milestone, touching off another sequence of bloody events.

To begin with, the Iranian regime must now be planning its answer to his death, to show that the position Soleimani spent so long creating outside its borders in the Middle East can be defended.

In other reaction:

• Iraq’s Prime Minister Adel Abdul Mahdi condemned the “assassination” of Soleimani as a “dangerous escalation” of regional tensions
• Russia said the attack was a “murder” and a “reckless step” by the US
• Lebanon’s Iran-backed Hezbollah group called for Soleimani’s death to be avenged
• Israel’s Prime Minister Benjamin Netanyahu said the US had the “right ” to defend itself and praised President Trump for acting “swiftly, forcefully and decisively”
• A spokesman for UN Secretary General Antonio Guterres said the world “cannot afford” another Gulf war

What has the US said?

The US has called the commander and the Quds Force terrorists, holding them responsible for the deaths of hundreds of US personnel.

Speaking on Friday afternoon, President Trump said Soleimani was “plotting imminent and sinister attacks” on US diplomats and military personnel in Iraq and elsewhere in the region.

“We took action last night to stop a war, we did not take action to start a war,” he said.

Earlier, the Pentagon said the US strike “was aimed at deterring future Iranian attack plans”.

The 3,000 extra US troops being sent to the Middle East are from the 82nd Airborne Division and they will join 750 troops from the same unit sent to Kuwait earlier this week following an attack on the US embassy in Baghdad.

How did the strike take place and who was killed?

Soleimani and officials from Iran-backed militias were leaving Baghdad airport in two cars when they were hit by several missiles from a US drone strike near a cargo area.

The commander had reportedly flown in from Lebanon or Syria.

Iran’s Revolutionary Guard said 10 people were killed, including five of its members and Iraqi militia leader Abu Mahdi al-Muhandis.

Muhandis commanded the Iranian-backed Kataib Hezbollah group, blamed by Washington for a rocket attack which killed a US civilian contractor in northern Iraq last Friday.

He also effectively led the Popular Mobilisation units (PM), an umbrella of militias in Iraq dominated by groups aligned with Iran.
