SANAA - At least 25 people were shot dead and hundreds wounded on Sunday when demonstrators camped in a square in Yemen's capital Sanaa tried to charge police lines in a dramatic escalation of protests against President Ali Abdullah Saleh.
A Reuters witness saw security forces firing at protesters from buildings overhead as well as using water cannon and tear gas to hold back tens of thousands of protesters, some wielding batons or throwing petrol bombs.
"Why are you still sitting here? Get moving everyone, move. Go defend the martyrs' honor," blared a voice on loudspeakers in Change Square, where thousands have camped out in ramshackle tents for eight months to demand and end to Saleh's 33-year rule.
