UN-backed efforts to bring aid to Homs and extract civilians were complicated by a series of live-fire incidents, with both sides in the conflict blaming each other. UN jeeps and Syrian Red Crescent trucks were halted by explosions blamed on mortar fire on February 8, as they entered the city’s besieged areas. On February 9, activists alleged that a muster point for civilians wishing to leave the rebel-held parts of the city was targeted.
