A bomb explosion has killed at least 3 people and wounded 7 others in northwest Pakistan as security is put on high alert across the flood-ravaged country.
Pakistani officials told Press TV that the bomb went off in a shop in a village in South Waziristan Agency, near the Afghan border, late on Saturday.
The wounded were shifted to local hospitals of the agency as police are investigating the cause of the explosion.
The incident comes a day after gunmen attacked Pakistani government buildings near the US consulate in the country's northwestern city of Peshawar, taking several soldiers hostages.
Later in the day, all four terrorists, who had taken two security men hostage, surrendered to security forces after a nine-hour siege.
Security was beefed up at all sensitive locations, including diplomatic missions in the cities, a Press TV correspondent reported late on Saturday.
"We are still trying to find out how militants entered in the territory and what their intended target is," Pakistan's Information Minister Khyber Pakhtunkhwa Mian Iftikhar Hussain said.
"They have been surrounded by security agencies and so far there are no casualties," he further explained.
The attacks took place while Pakistani officials warn of a significant increase in the death toll from the heavy flooding in the worst affected areas.
The officials have also estimated that the number of Pakistanis affected by the floods and in need of relief aid will continue to rise.
