State Dept. urges Americans in Syria to leave immediately

The State Department is urging all Americans still in Syria to leave immediately.

This, as the Syrian government intensifies its military assault on the city of Hama -- flashpoint of the opposition movement.

Video posted to social media sites on Friday shows smoke rising from buildings as people duck for cover amid continued shelling.

Activists say 24 people were killed.

The State Department says Americans who must remain in Syria should limit their travel.
