The attack is the latest response to a shooting by a lone militant that killed two American soldiers and a US civilian interpreter.
US and allied forces carried out “large-scale” strikes against the Islamic State jihadist group in Syria on Saturday, the US military said, in the latest response to an attack last month that left three Americans dead.
Washington said a lone gunman from the militant group carried out the December 13 attack in Palmyra – home to Unesco-listed ancient ruins and once controlled by jihadist fighters – that killed two US soldiers and a US civilian interpreter.
