BEIRUT (AP) — Opposition forces targeted Damascus with mortars, a roadside bomb and a suicide attack on Sunday as they pressed ahead in their quest for the seat of President Bashar Assad’s power.

Outside the capital, government troops battled rebels for the fifth straight day for control of a key highway. Both sides consider the fight for Damascus the most likely endgame in a nearly two-year-old civil war that has already killed more than 60,000 people.
