A Taliban suicide bomber has detonated a vehicle packed with explosives outside the house of a senior police official in Pakistan's southern city of Karachi, killing at least eight people.
Monday's attack killed six police officers guarding the police official's house. A teacher and her son, who were passing by, were also killed in the blast.
The Pakistan Taliban claimed responsibility for the bombing, which targeted Senior Superintendent of Police Chaudhry Aslam.
Aslam escaped unharmed and later told reporters that he will not be deterred by Monday's "cowardly act."
