DAMASCUS, Syria (AP) — Syria's interim government on Monday announced the end of a days-long military operation against insurgents loyal to ousted president Bashar Assad and his family in the worst fighting since the end of the 13-year civil war in December.

Syria's interim government signed a historic agreement Monday with the Kurdish-led authority controlling the country's northeast, a significant step towards national unity. The deal includes a ceasefire,

Residents described shootings outside their homes and bodies in the streets in Syria’s worst unrest since Bashar al-Assad’s ouster. More than 1,000 people have been killed since Thursday, a war monitor said.

The government of Syria says it has ended an operation in the coastal governorates of Latakia and Tartous after four days of fighting between security forces and pro-Assad armed fighters. The unrest came only three months after the fall of Syria’s Bashar al-Assad in an offensive by opposition fighters.
