PESHAWAR, Pakistan: A bomb planted at an electricity tower on Friday killed two passers-by in Pakistan's northwestern city of Peshawar, police said.

The explosive attached with a time device exploded when the victims were close to the electricity tower in the Badh Bher area of Peshawar, the capital of Khyber Pakhtunkhwa province, which borders Afghanistan.

"Two kilograms of explosives were used for the blast which killed two people," Javed Khan, a local police official told AFP.

The electricity tower was also damaged as a result of the blast.

Peshawar is vulnerable to bomb blasts and Taliban attacks as it runs into the semi-autonomous tribal belt, considered a safe haven for Taliban, Al-Qaeda and other insurgents fighting both in Pakistan and across the border in Afghanistan.

Pakistan says 35,000 people have been killed as a result of terrorism since the 9/11 attacks and the 2001 US-led invasion of Afghanistan.
