Islamabad - A powerful blast in north-western Pakistan on Monday killed at least five people and wounded several more, police said.
The bomb detonated along a busy road in the militancy-prone town of Dera Islmail Khan, a police officer, Zafar Rehman, said.
"Initial reports say five people are dead," Rehman told Deutsche Presse-Agentur dpa on the phone. He failed to give any figures for the injured.
However, private news channels reported that 20 people were wounded and the blast was caused by explosives planted on a bicycle left by the roadside.
