US strikes Iran-backed group in Syria after deadly attack on coalition base

Airstrikes in retaliation to attack on base in north-east by suspected Iranian-made drone that killed US contractor

The US military has carried out airstrikes against Iran-backed forces in retaliation for an attack that killed an American contractor and wounded five US troops.

A day after the deadly attack on US personnel in Syria, which Washington blamed on a drone of Iranian origin, sources said a US base in Syria's north-east was targeted in a new missile attack. US officials said there were no US casualties in the incident on Friday.
