Shooting and tear gas in Yemen unrest
Deadly clashes have been continuing in the Yemeni capital Sanaa amid a crackdown on anti-government protesters.
There has been growing anger at the government of President Ali Abdullah Saleh even though he has been out of the country since June 2011.
At least 50 protesters are thought to have died in Sanaa and elsewhere since government snipers opened fire on Sunday.
