An Israeli magistrate's court issued an eight-month imprisonment verdict against Palestinian political prisoner Samer Issawi, 33, who has been on hunger strike for 214 consecutive days, his sister, Sherine, said on her Facebook account on Thursday.

In October 2011, Issawi, then serving the nineth year of a 30-year jail sentence for involvement in resistance activities against Israel, was released as part of an Egypt-brokered prisoner swap between Hamas and Israeli authorities. That deal led to the release of captured Israeli soldier Gilad Shalit in exchange for more than 1,000 Palestinian prisoners held in Israeli jails.

However, Issawi was rearrested in July of last year under Israel’s so-called administrative detention law.

The law, which has been in place since the end of the British mandate in Palestine in 1948, allows for the arrest of Palestinians if they are deemed a "threat" to Israel's national security.

The scope of the ongoing hunger strike has posed a new challenge to the Tel Aviv regime, which has come under international criticism for its practice of detaining prisoners without trial.
