Syrian troops backed by tanks and artillery moved into a rebel-held district of Damascus on Monday, stepping up efforts to drive opposition fighters from the capital and build on battlefield gains elsewhere in the country, a rebel commander said.
Opposition sources said troops loyal to President Bashar al-Assad advanced into the neighborhood of Qaboun after subjecting the Sunni Muslim district to heavy shelling.
Videos posted on the internet show heavy smoke coming from a neighborhood in Sebeneh district.
Other clips show the rebel-held Qaboun district under heavy shelling -- smoke can be seen rising from several locations, and explosions can be heard.
Al Arabiya cannot independently verify the content of the videos.
More footage from the eastern Deir al Zour province shows a car set ablaze, reportedly after coming under fire from an Assad sniper.
More than 90,000 people have died so far in the more than two years of conflict.
