3 Pakistani soldiers killed in explosion

Three Pakistani soldiers were killed Saturday after a bomb planted on a roadside exploded in a northwestern tribal area, security officials said.

The blast took place at Katasarai village in restive Kurram tribal district bordering Afghanistan where Pakistani army and paramilitary forces have launched an operation against Taliban militants.

"Three security personnel including a lieutenant have embraced martyrdom and one other was wounded in an IED (improvised explosive device) blast," a senior security official said.

Local intelligence officials suspect the involvement of Taliban militants in the attack.
