Pakistan airstrikes kill about 100 militants in tribal regions

Pakistani intelligence officials say that airstrikes overnight in the northwestern tribal regions bordering Afghanistan have killed as many as 100 militants.

Two intelligence officials said Sunday that the airstrikes by the Pakistani military targeted eight militant hideouts in the North Waziristan tribal area.

The officials did not want to be identified because they were not authorized to speak to the media.

The information could not be independently verified.

The tribal areas are a remote and dangerous area that is difficult for journalists to access.

The airstrikes come a week after militants attacked the airport in Karachi in a five-hour siege that ended with 36 people including the 10 attackers killed.
