Iraqi security forces fired teargas on Tuesday outside the U.S. embassy to disperse protesters who had gathered to condemn American air strikes in Iraq. Only a small amount of teargas was used and militia forces, using loud speakers, urged the crowd to disperse, a Reuters witness said. The U.S. ambassador to Iraq and other staff were earlier evacuated because of safety concerns. Iraq PM demands protesters leave US embassy 'immediately' Iraq's caretaker premier Adel Abdel Mahdi said Tuesday that crowds that had stormed the US embassy in anger at Sunday's deadly US air strikes should leave the compound "immediately." Demonstrators had breached the embassy walls in protest at the US strikes that killed at least 25 fighters from a hardline pro-Iran faction known as Kataeb Hezbollah. "We recall that any aggression or harassment of foreign embassies will be firmly prohibited by the security forces," Abdel Mahdi's office said several hours after the attack began.
