Two buses carrying Pakistani navy officials were hit in Karachi killing four people while in Bluchistan, armed men attacked and set fire to a passenger bus killing at least 13 people

Two buses carrying Pakistani navy officials were hit in Karachi Tuesday, killing four people and wounding nearly 60 people when remote-controlled bombs exploded beside the buses at rush hour in different parts of Pakistan's politically tense economic capital, used by NATO to ship supplies to troops in Afghanistan.
  
Officials said four people were killed in the attacks and the navy, which is based largely in Karachi, identified them all as its employees.

Provincial government official Sharfuddin Memon told AFP that the first bomb was planted on a motorbike parked in the upmarket Defence Housing Scheme and the second hidden in rubbish in the impoverished Baldia town neighbourhood.
  
In the neighbouring province of Baluchistan, armed men attacked and set fire to a passenger bus late Monday, killing at least 13 people. Local police official Akbar Shahwani told AFP that those burnt alive included four children and three women.
