KARACHI: A car-borne Taliban suicide bomber flattened the house of a senior counter-terrorism police officer in Karachi on Monday, killing eight people including six policemen.

Senior Superintendent Aslam Khan, who was unhurt in the attack but whose home was destroyed, told AFP he had been threatened by the Pakistani Taliban and knew that he was the target.

The militant group claimed responsibility for the attack and said Khan had been targeted for arresting, torturing and killing Taliban members.

Khan heads the counter-terrorism unit of the Police Crime Investigation Department in Karachi, investigating Islamist militant cells in the port city of 18 million people, which is a vital hub for Afghan-bound Nato supplies.

“It was a car bomb attack on my house,” he said. “I was receiving threats from Tehreek-e-Taliban (TTP). Taliban are involved in this attack.” Several neighbouring houses were also wrecked in the attack, an AFP reporter saw, with four cars being badly damaged and a two-metre deep crater left in front of Khan’s home.

An AFP reporter at the scene saw rubble, mud and pieces of glass scattered over a large area in the upscale residential neighbourhood.

“Eight people including six policemen have been killed and several others were wounded,” Shoukat Hussain, another senior police officer, told AFP. “A child and a woman were also killed. It was a car suicide attack.” Speaking to reporters outside the remains of his one-storey bungalow, Khan said: “I woke up from sleep and saw fire around. I ran towards the other rooms of the house and saw my family safe but bewildered.

“This was a cowardly act of Taliban. I am not scared of Taliban. Let me tell you that I will not spare them in future.” Karachi city police chief Saud Mirza confirmed that Khan had received TTP threats, including one recent written threat.

“We claim responsibility for the attack. Aslam Khan has killed a number of our colleagues and also arrested and tortured many more,” TTP spokesman Ehsanullah Ehsan told AFP in a phone call from an undisclosed location.

“He was on our hit list and he is still on our hit list,” Ehsan said, giving names of several other police and crime investigation department officials also targeted. “They will be killed soon,” he vowed.

The TTP has members across the country and the attack was planned by a local branch, Ehsan added.

Witness Naeem Shaikh said he was taking his children to school when he heard a huge explosion.

“I went across a lane and saw this house destroyed and huge flames around it,” said Shaikh, who lives in the area.

He saw the bodies of a boy, later identified as a second-year school pupil (aged eight or nine), and his mother lying near the house. “The boy’s schoolbag was lying abandoned nearby,” Shaikh said, choking.

Karachi, Pakistan’s economic hub, is currently undergoing its worst ethnic- and politically-linked unrest in 16 years, with more than 100 people killed in one week alone last month.

The gang wars have been linked to ethnic tensions between the Mohajirs, the Urdu-speaking majority represented by the Muttahida Qaumi Movement, and Pashtun migrants affiliated to the rival Awami National Party.

The nationally ruling Pakistan People’s Party, which was elected in 2008 after nine years of military rule, insists that civilian authorities are capable of controlling the bloodshed, despite calls for military intervention.
