A loud explosion has been heard near the office of Rescue-15 here on Saturday.

Two policemen were killed after a young man carried out a suicide attack against Rescue 15, a police helpline unit, in the federal capital on Saturday. At least four other policemen were injured. The attack on the Rescue 15 in Sector G-8, 10 days after the one in Lahore last month, took place around 8.35pm, barely 24 hours after a bomb blast in a mosque in Dir, NWFP.

Sources said that intelligence agencies had warned about the attack, saying that some terrorists, including suicide attackers and five explosives-laden vehicles, had entered the capital. The suicide bomber, wearing a vest filled with three or four kilograms of explosives, somehow evaded police lookouts on the roof and the front and back entrances, entering the premises through a gaping hole in an under-construction wall behind the building.

When a police guard, Constable Imtiaz, spotted him and asked to prove his identity, he ran towards the Moharrar’s office and blew himself up.

The suicide bomber and Constable Munawar, the night shift Moharrar, were killed instantly. The deputy Moharrar, Salahuddin, police guard Imtiaz, and three other policemen Ramzan, Anwar, Tariq were injured.

Interior Minister Rehman Malik said the attack was a reaction to the Swat operation, adding that security agencies were fully alert. He said that eight of the 50 would be suicide bombers sent by the chief of the outlawed Tehrik-i-Taliban Pakistan, Baitullah Mehsud, had been arrested.

President Asif Ali Zardari condemned the suicide bombing and said that such acts of barbarism would not deter the government from going after the militants.

‘Militants, who are on the run, have become desperate but they will not escape their ignoble end,’ an official statement quoted the president as saying.

Praising the policemen who laid down their lives in the line of duty, the president said that such attacks ‘only strengthens the resolve of the people and the law enforcement agencies to wipe out extremism and militancy.’
