BEIRUT — Witnesses say Syrian pro-government protesters have attacked the U.S. embassy compound in Damascus, causing damage.

The witnesses said the protesters smashed windows and raised a Syrian flag on the compound today. They also wrote anti-US graffiti referring to the U.S. ambassador as a “dog,” the witnesses said.

The protests were over visits by the U.S. and French ambassadors last week to the opposition stronghold of Hama in central Syria.
