Two bombings killed four people on Tuesday in a restive northwestern Pakistani tribal area where the army is fighting militants, officials said.
  
The bombs went off at Painda Cheena village in the lawless Khyber tribal district, where the army is mounting an operation against the Taliban and other insurgent groups. In the first bombing two paramilitary soldiers and a civilian were killed, while the second blast, at the same place, killed another civilian during rescue work.
  
"Two paramilitary soldiers and a peace committee member were killed after a bomb planted on a roadside exploded," a security official told AFP. "After some time a second bomb exploded when people were busy in rescue work. The second blast killed a local tribesman and wounded two paramilitary soldiers."
  
Local government official Tayyab Ali confirmed the casualties. No group immediately claimed responsibility.
