Roadside bomb in NW Pakistan kills 1 soldier

A roadside bomb hit a security convoy in northwestern Pakistan, killing at least one soldier Thursday and wounding six others, police said.

The Pakistani security forces were driving in the Hangu district of Khyber-Pakhtunkhwa province when the bomb exploded, police official Amir Khan said.

No one claimed responsibility, but attacks on troops are usually blamed on the Taliban or other Islamist extremists that operate in the area, which has also seen sectarian clashes between majority Sunni and minority Shiite Muslims.

The latest explosion came as Pakistan's interior minister claimed that the majority of explosives come from across the border in Afghanistan. Rehman Malik was speaking at a national conference on reducing homemade bombs known as improvised explosive devices or IEDs.

"IEDs are actually being transported from Afghanistan to Pakistan," Malik said. "They are manufactured there and with the naked eye you can see on the border ... that terrorists are coming toward Pakistan along with arms and ammunition."

Afghanistan and Pakistan have each blamed the other in the past for roadside bombs.

U.S. and NATO troops in Afghanistan have said that the Taliban and other insurgents use safe havens in Pakistan to plot attacks across the border and also bring in explosives through Pakistan.
