Foreign ministry says raid close to Iraqi border 'serious violation of Syria's sovereignty'.
Egypt on Tuesday slammed a US airborne raid on a Syrian village close to the Iraqi border in which several people were believed to have died as a "serious violation of Syria's sovereignty".
A foreign ministry spokesman voiced "Egypt's concern following the military operation carried out by American forces on Syrian territory", in a statement carried by the official MENA news agency.
"Egypt considers this operation to be a serious violation of Syria's sovereignty," the foreign ministry said.
Egypt called for those concerned "to refrain from any activity or measure that could destabilise the region... and respect the principles of good neighbourliness".
Syria has accused the United States of "terrorist aggression" over the weekend raid in which Damascus says eight civilians were killed, including children.
An official in Washington said US forces had carried out a successful operation against "foreign militants".
