Prominent hunger-striking Palestinian prisoner Muhammad Allan was transferred to solitary confinement on Saturday, Palestinian prisoners solidarity network Samidoun reported.

Samidoun quoted prisoners’ rights group, Muhjat Al-Quds, as saying that Allan, who was detained by Israeli forces on 8 June and began his hunger strike that same day, was transferred from the Jalama detention centre on Saturday to Megiddo prison, where he was reportedly placed in solitary confinement.

Israel Prison Service (IPS) spokesperson Hana Herbst said hunger striking constituted “a disciplinary violation in prison and is treated respectively,” adding that IPS “transfers prisoners regularly according to management and operational decisions.”

Allan, a lawyer from the Nablus-area village of Einabus in the northern occupied West Bank, was released from prison in November 2015 after spending a year held under administrative detention during which time he carried out a gruelling 66-day hunger strike in protest of his detention.

On Thursday, an Israeli military court charged Allan with “incitement” on social media. His father told Al-Quds news website that Israeli forces “have been after his son to detain him and take revenge on him since the day he was released last year from administrative detention.”
