QUETTA, Pakistan – The death toll from a Pakistani Taliban suicide attack on a Shiite Muslim procession rose to 65 Saturday as critically wounded people died in hospitals, while a suspected U.S. missile strike killed seven insurgents in a restive tribal area.

About 150 people were wounded and some remained in critical condition after the bombing Friday in the southwestern city of Quetta, police official Mohammed Sultan said.

The attack was the second in a week against Shiites for which the Pakistani Taliban claimed responsibility. A triple suicide bombing Wednesday killed 35 people at a Shiite ceremony in the eastern city of Lahore.

“Our war is against American and Pakistani security forces, but Shiites are also our target because they, too, are our enemies,” Pakistani Taliban commander Qari Hussain Mehsud said.

He said he was proud the U.S. had added the Pakistani Taliban to its international terrorism blacklist Wednesday and threatened attacks in the U.S. and Europe.

Shiite leaders blamed the government for failing to protect them and called a general strike in Quetta, where all schools were closed for a day of mourning. Shiites make up an estimated 20 percent of the population in the mostly Sunni Muslim country, although figures are imprecise and disputed.

Long-standing sectarian violence in Pakistan, particularly against Shiites, has been exacerbated by the rise of the Sunni extremist Taliban and al-Qaida movements.

Interior Minister Rehman Malik said the Taliban, al-Qaida and the outlawed Lashkar-e-Jhangvi militant group were working together to destabilize Pakistan.

Meanwhile, two U.S. missiles fired from unmanned aircraft hit a house and a vehicle Saturday evening in a village near Miran Shah, the main town in the North Waziristan tribal region, officials said. The attack killed seven militants, four of them foreigners.
