At least eight people were killed and a dozen wounded when a bomb exploded in a market in a northwest Pakistan town.
The blast hit Dera Ismail Khan, about 300km south of the provincial capital Peshawar and near a district where Pakistani troops are locked in an offensive with Taliban fighters.
Officials said the bomb had been planted in a cycle rickshaw in a busy market and many people had been injured.
Pakistan has been hit by a string of deadly bomb blasts in recent weeks, many of them claimed by the Taliban, who say they are exacting revenge for a punishing military offensive against them across swathes of the northwest.
Security forces launched their campaign in three northwest districts around the Swat valley on 26 April after Taliban fights advanced towards Islamabad.
Operations recently expanded to Bannu district - just north of Dera Ismail Khan - while fighter jets have also bombed militant targets in the nearby semi-autonomous tribal area of South Waziristan.
Drone attack
Elsewhere, a suspected US drone aircraft has fired a missile at a vehicle carrying Taliban in Pakistan's South Waziristan region, killing three militants.
The attack hit in the Laddha region of South Waziristan, where the US alleges Al-Qaeda and Taliban rebels who fled Afghanistan after the 2001US-led invasion are holed up, plotting attacks on Western targets.
The US military does not, as a rule, confirm drone attacks, but its armed forces and the Central Intelligence Agency operating in Afghanistan are the only forces that deploy drones in the region.
Pakistan publicly opposes drone attacks, saying they violate its territorial sovereignty and deepen resentment among its people.
Since August 2008, more than 40 such strikes have killed around 420 people.
The last suspected US missile strike hit on 16 May, killing 25 people
