Dozens of Palestinian prisoners have contracted coronavirus inside an Israeli-run prison, the Palestinian Committee of Prisoners' Affairs said Tuesday. 

More than 80 prisoners have tested positive for the coronavirus at Gilboa prison in central Israel, which houses some 360 Palestinian detainees, the committee said. The Israeli Prison Service has canceled prison visits in response to the outbreak, and announced plans to move the infected prisoners to the Tzalmon detention center in the Galilee. Haaretz reported that the prison service said at least 56 prisoners had tested positive.

Hamas spokesperson Hazem Qassem blamed the outbreak of coronavirus on Israel’s "deliberate medical negligence.” A Hamas source that spoke to the Palestinian Al Quds newspaper said the militant group “would not remain silent” if prisoners were further exposed to the virus. 

The ward where the infections emerged was used mostly for Hamas suspects, Haaretz reported. According to the outlet, the prisoners claim they were infected by one of the wardens. Hamas leader Abbas al-Sayed is among those infected, his wife told Turkey’s Anadolu Agency.
