BEIRUT (AP) — Syrian fighter jets bombed a Palestinian refugee camp in Damascus Tuesday for the second time this week after rebels made significant advances, seizing large areas within the camp, activists said.

Meanwhile, American foreign correspondent Richard Engel of NBC said that he and his crew escaped unharmed during a firefight after being held captive for five days by pro-regime gunmen.

The rebels fighting to topple Assad's regime have pressed hard against the regime in the past weeks, capturing air bases and military installations in and around Damascus.
