A Palestinian doctor abducted by Israeli forces from Gaza City’s al-Shifa Hospital has died in their custody, the Palestinian health ministry said on Wednesday.

Ziad Mohammed al-Dalou, an internal medicine physician, is the third doctor to die in Israeli jails, where widespread torture has killed at least 60 Palestinian prisoners over the past 11 months.

Dalou was detained on 18 March from al-Shifa Hospital, along with dozens of other health workers, when Israeli forces raided the facility in a two-week-long assault.

The deadly raid decimated the hospital, which had been the largest and most equipped medical facility in the Gaza Strip. After the Israeli forces withdrew, dozens of bodies were found buried in mass graves in the hospital’s courtyards.

According to the Palestinian health ministry, Dalou was detained while performing his duties at the hospital.
