Prominent Bahraini human rights activist Abdulhadi al-Khawaja, who has been imprisoned by the regime, has reportedly gone on hunger strike.

Al-Khawaja was sentenced on 22 June 2011, along with eight other activists, to life imprisonment for his influential role in the 2011 protests against the Al Khalifa regime.

Al-Khawaja’s daughter, Maryam al-Khawaja, tweeted that her father “has started an open ended hunger strike” in protest of the continued arbitrary detentions and the collective punishment in the form of new rules.

“We're waiting to hear from him when he's allowed to call to get more information,” she tweeted, adding that her father’s health is deteriorating and a hunger strike may quickly put him at risk.

Bahraini regime denies the detainees access to medical care, cancels hospital appointments, forces prisoners to wear shackles once outside their cells, and severely limits family visits.

Human rights activists warned last month against the new restrictions, stressing that the conditions had dramatically deteriorated at Jaw prison.

Ever since a popular uprising began in Bahrain on February 14, 2011, anti-regime protesters have held demonstrations on an almost daily basis.

The protesters demand that the Al Khalifa ruling regime relinquish power and a just system representing all Bahrainis be established.
