Four persons were killed and 13 others injured on Monday when a bomb exploded at a crowded bus stand in Kohat town of Pakistan's troubled North West Frontier Province.
The blast which took place at the Teera bazar area in the town was the latest in a series of terror attacks across the NWFP since the Pakistan army intensified military offensive in the region.
Taliban which suffered reverses in the battle against the army have vowed to carry out attacks in Pakistani cities in retaliation against the operations.
Authorities declared an emergency at local hospitals as the wounded were rushed there. Officials of the bomb disposal squad and security agencies inspected the site of the blast. No group claimed responsibility for the attack.
Prime Minister Yousuf Raza Gilani condemned the blast, saying those involved in such attacks were enemies of the state and would be brought to justice. He said the government would eradicate terrorism from the country at all costs.
