A Taliban leader who sanctioned the assassination attempt on Malala Yousafzai has escaped military prison, Pakistani officials said Monday.

Ehsanullah Ehsan, a former figurehead for the Taliban in Pakistan, posted on social media that he had escaped prison.

After the Reuters asked whether it was true, Pakistani Interior Minister Ijaz Shah said: “That is correct, that is correct.”

Ehsan claims he had fled to Turkey, however, the Pakistani officials weren’t able to verify that, the AFP reported.

He has claimed responsibility for conducting numerous Taliban attacks, including the assassination attempt on Malala.

Malala was shot in the head on Oct. 9, 2012, while traveling on a bus from school in her hometown of Mingora. Fortunately, she survived the attack and was later awarded the Nobel Peace Price in 2014 for her work in advocating for young girls’ rights to education.

The militant Ehsan later surrendered to authorities in the year 2017 and later gave high-profile interviews on Pakistani television.

As of now, It remains unclear how Ehsan managed to escape from a maximum-security prison.
