BEIRUT — Syrian troops have advanced into rebel-held areas of the city of Homs, occupying buildings after pummeling the area with artillery that drove out opposition fighters, an activist said on Saturday. The push into Khaldiyeh district was the first significant gain for troops loyal to Syrian President Bashar Al-Assad, who have been waging an eight-day campaign to seize parts of the central Syrian city in rebel hands for over a year. Tariq Badrakhan, an activist based in the neighborhood, said government troops used rockets, mortars and cannon fire to flush out the area's “first line of defenses” on Friday evening. The offensive continued Saturday morning, he said via Skype, as explosions were heard in the background. “We feel like they are shaking the sky,” Badrakhan said. Another activist said eight rebels were killed in the fighting. He requested anonymity because rebels have accused him in the past of damaging their morale by reporting their casualties. Government forces, sometimes bolstered by fighters of the Lebanese Shiite militia Hezbollah, have launched a major countrywide offensive to reclaim territory lost to rebels, who operate in chaotic groups with ideologies ranging from secular to hardline Islamic extremists. In other violence Saturday, government troops battled rebels in the Damascus suburb of Qaboun, as the regime tries to push opposition forces further away from the capital, the British-based Syrian Observatory for Human Rights said. State-run television said government forces seized control of the area, adding that the move had cut off rebel weapons supplies and movement between the neighborhoods of Jobar, Qaboun, Zamalka and Harasta. — AP
