US military groups deployed smoke and gas to disperse the protestors who gathered at the embassy following an attack on a hospital in Gaza. On Tuesday, thousands of Lebanese protesters, some waving Palestinian flags, gathered outside the US embassy. Objectors complained about the price tag and the size of the embassy given so few Americans travel to Lebanon. In the occupied West Bank city of Ramallah, Palestinian security forces fired tear gas and stun grenades to disperse protesters throwing rocks and chanting against Abbas as popular anger boiled over after the blast. Clashes with Palestinian security forces broke out in a number of other cities in the West Bank, which is ruled by Abbas' Palestinian Authority, late on Tuesday, witnesses said.
