ISLAMABAD, Pakistan - A police officer was killed and at least 26 people wounded yesterday when two car bombs detonated within 25 minutes and a dozen feet of each other in the southern port city of Karachi, police officials said.
The explosions came days after six men accused of being part of a banned militant group were arrested in the city. And the location of the blasts, at the gate of an English-language training school, prompted officials to say that the attackers could have been lashing out at Pakistan's aligning with the United States to fight terrorism.
