Bomb planted outside store kills 4, wounds 21 in NW Pakistan

PESHAWAR, Pakistan - A homemade bomb placed outside a store in northwestern Pakistan where locals watch movies exploded, killing four people, including a child, officials said.

The attack, which also wounded 21 people, occurred Thursday on the outskirts of Peshawar, a city near the Afghan border that experienced a wave of bombings at the end of last year but has been fairly quiet in recent months.

Officials earlier said the explosion was caused by three suicide bombers who were attempting to attack a security convoy. It was unclear what prompted the erroneous report.

The shop that bore the brunt of the blast often screened movies on a large television, said Liaquat Ali Khan. The explosion also damaged three other shops nearby, he said.

Two men were killed instantly, while two others, including a child, succumbed to their injuries at a local hospital, said medical official Jamal Shah.

The bomb appeared to contain some 11 pounds (5 kilograms) of explosives, said police explosives expert Shafqat Malik.

Pakistan has been plagued by a Taliban-led insurgency that has killed thousands of people over the past few years, many of them in the volatile northwest. The government has fought back with a series of military offensives to deny militants sanctuary along the Afghan border.

The largest operation so far was launched in October in the South Waziristan tribal area, the major stronghold of the Pakistani Taliban. The ground invasion sparked a wave of attacks that killed over 600 people, many of them in Peshawar.

The decline in attacks since the beginning of the year may indicate the military operations have had some success in disrupting the militants' activities.
