A woman was killed and two children injured after a cluster bomb exploded in the suburbs of Mosul, 400 kilometres north of Baghdad, dpa quoted security officials as saying Tuesday. General Zenon al-Sabaawy told the German Press Agency dpa that the bomb was a remnant of a previous war. In a separate incident in Mosul, a civilian was killed by gunmen who escaped. Meanwhile, a policeman in the same city also died after four gunmen broke into his house, said al-Sabaawy.
