Special operators just rescued a high-profile prisoner from al-Qaeda

Ali Haider Gillani, the son of an ex-Pakistani prime minister, was rescued by U.S. special operators and Afghan commandos in a joint operation in Paktika province May 10.

The strike force killed four enemy combatants in the raid with no reported loss to friendly forces. Gillani was unharmed in the rescue mission.

The focus of the operation, "was to go after al-Qaida-related targets in the area, and there was an indication that there may have been a hostage being held with them," U.S. Army Brig. Gen Charles Cleveland told the AP. "So it was a nice surprise to get that."

Gillani and his father are members of the Pakistan People's Party, a group which has sponsored and led several major offensives aimed at Islamic militants.

Gillani was originally kidnapped in May 2013 while campaigning for the Punjab provincial assembly. Pakistani leaders are often threatened or attacked by the Pakistani Taliban, especially if the leaders are perceived as likely to threaten the Taliban.

The kidnappers had been attempting to negotiate the release of several high-profile al-Qaeda prisoners in exchange for Gillani's safe return.

Gillani was flown to Bagram for medical evaluation and is scheduled to return to Pakistan once cleared by doctors.

The raid was conducted as part of Operation Freedom's Sentinel, the current campaign of America's mission in Afghanistan. It is part of NATO's Resolute Support Mission.
