PROTESTERS angered by an anti-Islam film have stormed the US Embassy compound in Yemen's capital, Sanaa, following the death of the US ambassador to Libya in protests on Tuesday night.
Protesters torched a number of diplomatic vehicles as security forces used water cannons and warning shots in a bid to drive them out.
Police had earlier fired warning shots to disperse few thousands of protesters as they approached the main gate of the mission.
"O, Allah's messenger... O, Mohammed," protesters chanted.
Before storming the embassy compound on Thursday, the demonstrators removed the embassy's sign on the outer wall and set tires ablaze. Once inside the compound, they brought down the US flag and burned it.
Yemen is home to Al-Qaeda in the Arab Peninsula and the United States is the main foreign supporter of the Yemeni government's counterterrorism campaign.
The government on Tuesday announced that al-Qaeda's No. 2 leader in Yemen was killed in an apparent US air strike, a major blow to the terror network.
In Cairo, police used tear gas against a stone- and bottle-throwing crowd protesting outside the US embassy.
The health ministry said 13 people were injured during sporadic clashes through the night outside the embassy.
Meanwhile, Egypt's Islamist President Mohamed Morsi slammed "attacks" on the Muslim prophet Mohammed, while also stressing that he condemned violence.
"We Egyptians reject any kind of assault or insult against our prophet. I condemn and oppose all who... insult our prophet," Morsi, on an official visit to Brussels, said in remarks broadcast by Egyptian state television.
"(But) it is our duty to protect our guests and visitors from abroad... I call on everyone to take that into consideration, to not violate Egyptian law... to not assault embassies," he added.
