Mahmoud Abu Shahada, the head of the orthopaedics department at Nasser Hospital, has been released, lawyer Khaled Zabarqa tells Al Jazeera Arabic, after an appeal was filed with the Israeli Supreme Court.

He was subjected to torture and harsh treatment at the hands of the military after being arrested during a raid on Nasser Hospital, in southern Gaza’s Khan Younis.

The Institute for Palestine Studies, which documents the killing and arrest of medical workers in Gaza, said he was detained on February 17 last year.

Zabarqa said Abu Shahada was kept under arrest despite it being clear that he had not taken part in fighting in Gaza.

The Palestinian Information Center has posted a video of what it says shows Abu Shahada’s reunion with his mother following his release.
