ISLAMABAD, Jan 18, IRNA -- Pakistani gunships shelled positions of suspected militants in North Waziristan tribal region early Thursday, residents said.
Local media also reported that the military helicopters hit several areas in Mir Ali, injuring several people.
Correspondents said that several houses were damaged during the operation.
There was no official word on the incident.
Sources said that the action was taken few days after a bomb attack on a military truck, killing at least three security men.
It was not clear which group was targeted in the early morning shelling.
There had been at least two attacks on the security forces in North Waziristan earlier this month, which had killed dozens of soldiers.
The main Taliban group in North Waziristan hd struck a peace deal with the government in 2007 but some other militant groups are blamed for attacks on the security forces.
Correspondents said that after the last week bomb attack, members of a local tribal peace council had tried to resolve the issue, but all efforts failed.
