Twin suicide bombs targeting security forces responsible for this week capturing senior Al-Qaeda operatives killed 26 people and wounded many others in southwest Pakistan Wednesday, police said. DIG FC Brig. Farrukh Shazad was also reported injured.

One attacker detonated his bomb-laden car outside the residence of the deputy chief of the Frontier Corps in Quetta city, before a second attacker blew himself up inside the house, said senior police official Hamid Shakil."twenty two people have been killed and 32 were wounded," he said.

"It was a twin suicide attack. The house was badly damaged... some members of the family were severely injured. The deputy inspector general himself is injured," he said.

Four members of the Frontier Corps were among the dead, including a senior officer, Shakil and a local security official said, and the wife of the deputy chief and two children were also killed.

The residence of the deputy inspector general is close to other government buildings and official residencies in the city of Quetta, the main town of Baluchistan province, which borders Afghanistan and Iran.

The Frontier Corps is Pakistan s paramilitary force, which took part in an operation on Monday to arrest a senior Al-Qaeda leader believed to have been responsible for planning attacks on the United States, Europe and Australia.

Younis al-Mauritani was picked up in the suburbs of Quetta along with two other high-ranking operatives after US and Pakistani spy agencies joined forces, according to the Pakistan army.

The arrests signalled another blow to the global terror network, four months after Al-Qaeda chief Osama bin Laden was killed in Pakistan by covert US forces, leading to a souring of ties between allies Islamabad and Washington.
