Pakistan’s Prime Minister, Shehbaz Sharif, has urged US President Joe Biden to release jailed Pakistani national, Aafia Siddiqui, Anadolu Agency reports. Sharif expressed concern in a letter sent to Biden on 13 October regarding Siddiqui’s fragile mental and physical health in prison, the local daily, Dawn, reported on Friday.

Siddiqui is serving an 86-year prison sentence in Texas for attempting to murder an American soldier in Afghanistan.

“Numerous Pakistani officials have paid consular visits to Dr Siddiqui […] all of them have raised their serious concerns about the treatment she has received,” Sharif stated, adding that they have expressed serious concerns about her treatment and fear she may commit suicide.

Siddiqui, who earned her PhD from Brandeis University, went missing in Pakistan in 2004 with her three minor children before being found in a US military base in Bagram, Afghanistan in 2008.

She was accused of attacking a US soldier during interrogation, which she and her family denied. In 2010, she was sentenced to prison by a US court.
