Even as the United States tries to usher Saleh out, his forces are still open firing on protesters who come too close to the presidential palace:

Security forces and plainclothes government supporters opened fire Monday on tens of thousands of protesters from rooftops, according to witnesses, as violent clashes spread for a second day through the central city of Taiz. At least 10 people were killed, according to the official Saba news agency; a doctor at a local hospital said 12 had died and 50 more were wounded in the gunfire.
The violence in Taiz, where tens of thousands have staged a sit-in for more than six weeks, was the deadliest yet seen there and came amid signs that the United States had concluded that President Ali Abdullah Saleh, a longtime ally, must be eased out of office. Protesters have demanded he step down immediately.
