The attack on the outskirts of Peshawar killed the leader of an anti-Taleban militia, Israr Khan, and two aides as he passed through a market in the village of Matni, said police official Khurshid Khan. Three more people were injured. The government supplies a string of militias with arms and money to fight the Taleban militants.

The deadliest blast was a suicide attack at a mosque in South Waziristan that killed 26 people and injured 40 more, said an intelligence official in the region.

It was the first significant suicide attack in Pakistan since Aug. 4 and comes with the country battling to cope with the fallout of devastating floods that have affected up to a fifth of the country and hit 20 million people.

“The death toll in the suicide attack has risen to 26, with more than 40 people wounded,” said one of the officials.

A health official in a paramilitary hospital in Wana said condition of most of the wounded was critical.

“We have received 14 injured but there condition was very critical,” the official said.

An official said Maulana Noor Mohammad, a former lawmaker who ran the school, was among the dead.

Yar Mohammad, a local tribesman who was present inside the mosque, also said it was a suicide blast.

The mosque was badly damaged in the blast, where local residents were busy trying to recover people from the rubble amid fears that the death toll could rise further.

There was no claim of responsibility, though militants have often attacked clerics or others who do not support them. It was unclear whether Mohammad fell into that category. Militant and tribal factions also fight among themselves.

Earlier, a bomb exploded inside a school during a meeting of elders in Kurram tribal region, killing seven people.

Local official Khalid Umerzai said the elders at the meeting were discussing a disagreement over ownership of the school building. It wasn’t clear if the blast was tied to that dispute or if it had been launched by militants.

The army has launched offensives in South Waziristan and Kurram over the last 18 months.

There is little or no government presence in either area.

South Waziristan was affected by the floods that have swept Pakistan over the past month, with 18 bridges washed away and about three dozen deaths in the tribal area.
