US and allies strike Islamic State in Syria after attack that killed three Americans

Military says it targeted the jihadist group throughout Syria in response to attack on US and Syrian troops in Palmyra

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 13 December attack in Palmyra, which killed two US soldiers and a US civilian interpreter. The area is home to Unesco-listed ancient ruins and was once controlled by jihadist fighters.
