Yemeni forces fired on demonstrators in three major cities Thursday, killing at least 18 people and wounding hundreds more. In the capital, Sanaa, republican guards fired on protesters who broke away from the designated sit-in area and marched on the cabinet building. Soldiers loyal to the defected general Ali Mohsin then arrived to the area in pickup trucks and returned fire to the republican guards—his first clash with government forces since siding with the opposition in March. Protesters are planning a march on the presidential palace Friday.
