"It's clear to us that it didn't have much substance to it," Toner said, adding that he thought the Syrian people would be disappointed.
"We would strongly condemn any violence against the protesters," the State Department spokesman added. Assad, who succeeded his father Hafez in 2000, has come under unprecedented domestic pressure over the past two weeks, with protesters defying emergency rule in public protests demanding more freedoms, emboldened by the wave of protest that has rocked the Arab world since December. The demonstrations, which began on March 15, were quickly contained in Damascus, but took root in the tribal region of Daraa, south of the capital. Gunfire could be heard in the port city following Assad's speech. But it is Daraa that has sustained the most casualties, with activists estimating that at least 100 people had been killed in just one day of clashes last week with security forces. Syrian human rights activists have accused security forces of killing 130 people in the crackdown. Amnesty International says upward of 55 people have been killed. Officials put the toll at some 30 dead.
