Trump confirmed there were US soldiers injured in Iran's missile strike earlier this month, though he had previously denied it.

"I heard they have a headache," US President Donald Trump told reporters at a press conference after the end of the World Economic Forum in Davos, Switzerland. "I can announce that the issue is not so serious."

Trump said he was aware of the wounded US troops a few days after Iran attacked the missile on January 8 against two US garrison bases in Iraq in retaliation for Washington's airstrike on killing Iranian General Qassem. Soleimani.

The news contradicted a previous assertion from President Trump that "no Americans were harmed, all soldiers were safe" in Iran's missile strike.

Soleimani, commander of the Quds task force of Iran's Islamic Revolutionary Guards, is considered the country's second most powerful man after supreme leader Ayatollah Ali Khamenei. His death strained relations between the United States and Iran with Tehran's vow of vengeance.

President Trump said Gen. Soleimani planned to attack four US embassies in the Middle East. However, US Defense Secretary Mark Esper said on 13 January there was no concrete evidence of this information.
