Bomb in Pakistan's Rawalpindi kills at least one

RAWALPINDI, Pakistan (Reuters) - A suicide bomber on a motorcycle attacked a bus carrying workers from a nuclear facility and blew himself up in the Pakistani city of Rawalpindi on Thursday, killing at least one other person, police said.

Pakistan has been hit by a wave of bombings in recent weeks in response to a military offensive against Taliban militants in the northwest of the country, but Thursday's was the closest to the capital since the launch of the offensive.

Rawalpindi, near Islamabad, is home to the headquarters of the Pakistani army and other state agencies.

Two other attacks in the country's northwest killed three people.

The city's police chief had originally told reporters that up to six people had been killed in the Rawalpindi blast, but he later revised that figure down.

"I was at the spot and was told the toll was five to six, but later we checked with hospitals and they confirmed one dead and 29 wounded," Nasir Durrani told reporters.

Senior police officer Rao Iqbal said the bus was carrying workers from a main nuclear facility, the Khan Research Laboratories.

Policemen at the scene shifted the mangled remains of a motorcycle from beside the bus, which had its windows blown out. Another policeman carried a plastic bag, apparently containing bits of human flesh.

In a separate incident, a roadside bomb exploded as a police patrol passed by on the outskirts of the northwestern city of Peshawar, killing two policemen and wounding four, including two civilians, senior police official Safwat Ghayur said.

In a suspected sectarian attack, a man lobbed a hand grenade at a butcher shop in the northwestern town of Dera Ismail Khan, killing one and injuring four, a senior police official said.

The army went on the offensive in the Swat region two months ago after the Taliban seized a district 100 km (60 miles) from Islamabad, raising alarm at home and among allies who need Pakistani help to fight al Qaeda and tackle Afghanistan's insurgency.

REDEPLOYING BORDER FORCES

The military says it is nearing the end of the offensive in Swat, but intermittent clashes have erupted as soldiers encounter pockets of fighters.

The military said on Thursday afternoon that 23 militants had been killed and five were captured in the previous 24 hours.

But no Taliban leaders have been among the approximately 1,600 militants the army has reported killed in Swat. Independent casualty estimates are not available.
