Damascus lashed out at Washington over charges that American forces killed at least eight civilians when US helicopters were on a mission to shut down insurgent 'rat lines.'
Syrian state media reported that four US helicopters entered Syrian airspace around 4:45 p.m. Sunday and struck a construction site in the al-Boukamal region.
An unnamed US military official quoted by the Associated Press (AP) confirmed the attack, saying the US was trying to shut down "rat lines" sending Al Qaeda-linked insurgents and other foreign fighters into Iraq from Syria.
The raid appears to be straining already tense US-Syrian relations, even as Syria has reached out to the Iraqi government and Lebanon, entered into indirect talks with Israel, and held talks with the European Union.
SANA, the Syrian Arab News Agency, quoting an unnamed "official media source," said the helicopters attacked a civilian site about five miles inside Syria, "leading to the martyrdom of eight citizens," including the building guard and his wife.
