US President Donald Trump, during his election campaign, had promised to free Dr Afridi from Pakistan if elected to office, bus been silent on the issue since being elected.

Osama bin Laden, the mastermind behind several terrorist attacks against US assets, including the 9/11 attacks in New York, was killed in an operation by the US Navy Seals on May 1, 2011. He was found to be living close to the Pakistan Military Academy (PMA), Kakul.
