Syria: 'There is a growing humanitarian problem'

At least 62 people have been killed across Syria as thousands of anti-government demonstrators rallied in several cities, activists say.

Witnesses and human right groups say many died when troops opened fire on protesters in the city of Deraa, where the unrest began in mid-March.

The security forces swamped the streets of the capital Damascus and tear gas was reportedly fired as prayers ended.

Matthew Price reporting from the Jordanian-Syrian border, says he has heard that "there is a growing humanitarian crisis and food and water supplies are running out" in Deraa.
