Syria monitors say rebels bombed a government building near Damascus on Sunday, killing 31.
The London-based Syrian Observatory for Human Rights says the building was destroyed. A spokesman tells the French News Agency that three generals and a brigadier general are among the dead.
The group also says Syrian forces launched a second straight day of air raids on the town of Qara in the mountainous Qalamoun region, close to the Lebanese border.
That region has the few remaining rebel supply lines between Syria and the outside world. But the bombings have forced several thousand Syrians to seek refuge in Lebanon, overwhelming small towns that cannot handle such a crisis.
