KARACHI, Pakistan (AP) -- Two car bombs exploded minutes apart by a language school close to the U.S. Consul's residence in Pakistan's biggest city Wednesday, killing a police officer and wounding 25 other people.

The attack came days after police in Karachi said they smashed an Islamic militant ring accused in a deadly bombing outside the U.S. Consulate two years ago and a failed assassination plot against Pakistan's pro-American president.
