The escalation of Yemen’s ongoing bloodshed is likely to add further fuel to public rage. The country has been roiled with protests for nearly three months, as protesters demand President Ali Abdullah Saleh to step down from more than three decades in power.

In the capital Sanaa, forces fired on tens of thousands of protesters as they marched to the cabinet building. Snipers killed two people in the industrial center Taiz, where security men used gunfire, tear gas and bats on protesters. In the Red Sea port city of Hudaida, protesters were fired on as they tried to force their way into a government building.

The number of dead is expected to rise.
