Shooting and tear gas in Yemen unrest

Government forces have opened fire for the second day in a row in the Yemeni capital, Sanaa.

At least 20 people have been killed, doctors say, in the crackdown which began on Sunday.

Snipers in Sanaa fired from rooftops at a protester camp, killing bystanders including a child, witnesses said.

And government forces have begun shelling areas held by soldiers loyal to the protesters, reports say.
