The United States has cut aid payments to Pakistan by $33 million, after Islamabad convicted a doctor who worked with the CIA to help track down Osama bin Laden of high treason.

The Senate Appropriations Committee decided to punish Islamabad $1 million for every year of Shakil Afridi's 33-year sentence.

The committee has already more than halved the amount President Barack Obama had earmarked for Pakistan, threatening further sanctions if the country remains uncooperative and continues to block NATO and U.S. forces from using overland supply routes to Afghanistan.
