Israeli security forces stand next to an overturned bus after a Palestinian man rammed an excavator into it, on August 4, 2014 in Jerusalem, killing one person and lightly injuring five others. The incident took place on the seamline between east and west Jerusalem and came as Israel pressed a major military campaign in Gaza which has killed more than 1,800 Palestinians. Police said the excavator had overturned a bus, prompting two police officers who were in the vicinity to open fire, killing the driver and foiling what they described as a "terrorist attack".
