Tehran was not involved in the drone attack on a US base in Jordan which left three service members dead and more than 30 wounded, Iranian Foreign Ministry spokesman Nasser Kanaani said on Monday. 

The Islamic Resistance in Iraq – an umbrella group for Islamist Shia militias – claimed responsibility for the strike on the outpost known as Tower 22, not far from the border with Jordanian-Syrian border.

Iran has denied involvement in a drone attack on a US base near Jordan's border with Syria that killed three US troops.

The US blamed the attack on "radical Iranian-backed militant groups" which also left dozens injured.

US President Biden vowed revenge and said: "We shall respond."

It is the first time that a strike has killed US troops in the region since Hamas's 7 October attack on Israel.

There have been other attacks on US bases in the region, but before Sunday there were no fatalities, according to the US military.

Tehran has denied any involvement in a drone strike that killed three US troops at a base in Jordan, near the border with Syria, after US President Joe Biden blamed Iran-backed militia and vowed revenge.

In a statement published by the state news agency Irna, Tehran’s UN mission said: “Iran had no connection and had nothing to do with the attack on the US base,” adding: “There is a conflict between US forces and resistance groups in the region, which reciprocate retaliatory attacks.”
