Pakistan's military launched a long-awaited offensive last month, aimed at wiping out longstanding militant strongholds in the North Waziristan tribal region, which borders Afghanistan.

The operation followed failure of peace talks between the government and Tehreek-i-Taliban Pakistan negotiators and a brazen Taliban-claimed attack on Karachi's International Airport.

More than 800,000 people have fled a major military offensive against the Taliban in a Pakistani tribal area, officials said Wednesday.
