Israel arrested Khader Adnan one day after releasing the Palestinian hunger striker from an Israeli prison. Adnan was arrested Monday when he was going to East Jerusalem to take part in a religious ceremony.

Adnan was arrested for not having proper documents to enter the Old City and taken to a police station.

The 37-year-old Palestinian protester was released from an Israeli jail Sunday. He had been arrested for staging a hunger strike against Israel’s practice of administrative detention.

Haaretz reported Adnan had earlier staged a hunger strike for 55 days. He told his friends and family he was going to at the al-Aqsa Mosque. The Israel Security Agency confirmed the detention, saying Adnan had entered Jerusalem without proper documents. The security agency, also known as Shin Bet, said Adnan had been refused entry into the country due to his alleged involvement in religious extremism.

Upon his release, Adnan received a hero’s welcome in his hometown of Arraba. Adnan started his hunger strike April 6 and ended it June 28. Israel agreed to release him two weeks after the hunger strike had ended. Press TV reported Adnan had been jailed for more than a year without trial or charge.

During Adnan’s hunger strike, his health worsened as he refused to take water and minerals. After his release, he was taken to a hospital in Jenin for a medical evaluation.

Adnan staged a 66-day hunger strike in 2012. Adnan has spent more than six years in Israeli detention altogether.

The Palestinian Prisoners Club said Israel detained 383 Palestinians across the West Bank in December.
