A year ago Pakistan launched the first of a series of major military assaults against the Taliban in the country's north-west.
The BBC's Syed Shoaib Hasan looks back at the anti-militant operations and how successful they have been.
On 26 April 2009, Pakistan army commandos stormed into Buner district in the North West Frontier Province.
The Pakistani authorities had been under growing pressure to take action after the Taliban took control of the district.
Under their leader, Maulana Fazlullah, the local Taliban had been expanding their power from Swat Valley, once a popular tourist area, to other parts of the region since 2007.
After the move into Buner, Pakistan's army declared all-out war.
Black Thunderstorm - as the Buner operation was called - was soon expanded into a fully-fledged military offensive.
