Pakistani officials said two bomb attacks killed at least five people in the country's restive northwest, reported The Associated Press.
The blasts in Chamarkand, a town in the Bajur tribal area, reportedly singled out anti-Taliban tribal leaders, according to The Wall Street Journal.
Tariq Khan said the roadside bomb killed two anti-Taliban tribal elders and the blast quickly drew security forces to the area, prompting a second bomb explosion nearby that killed two soldiers and a policeman, reported Agence-France Press.
AP said the bombs appeared to have been set off by remote control.

No group has so far claimed responsibility for the attack, but the Bajur region lies near the Afghan border -- a mostly lawless region seen as a haven of militant activity.
Large military campaigns were launched against the Taliban in Bajaur in August 2008 and February 2009, said AFP.
