Four Killed In Renewed Shelling Of Syrian City

BEIRUT (AP) - Syrian activists say government troops have resumed shelling rebel-held areas in central Syria, killing at least four people.

The Baba Amr neighborhood of Homs has been under siege for three weeks. The British-based Observatory for Human Rights says troops also have tried to storm a rebel-held town just north of Homs. Activists report heavy fighting between troops and army defectors who destroyed two armored personnel carriers.

The U.N. estimated in January that 5,400 people had been killed in the conflict in 2011. Hundreds more have died since, and Syrian activists say the death toll is now more than 7,300.
