The son of a former Pakistani prime minister who has been in custody of al Qaedafor over three years was rescued during a joint counterterrorism raid by American and Afghan special operations forces on Tuesday.

Ali Haider Gilani, son of Pakistani Prime Minister Yousuf Raza Gilani, was being held in a suspected al Qaeda compound in the Giyan district of eastern Afghanistan’s Paktika province when U.S. and Afghan commandos raided the compound, according to a Defense Department statement.

“Four enemy combatants were killed as a result of the operation. No other injuries or damage was observed or reported,” Pentagon officials said.

Pakistan Foreign Ministry confirmed Gilani’s rescue after being informed of the operation by Afghan National Security Adviser Mohammad Hanif Atmar, according to local reports.
