Israeli troops killed a youth at a hospital and read out Jewish prayers at a mosque in the occupied West Bank city of Jenin during raids that Palestinian authorities said on Thursday killed 12 and that Israel said helped capture dozens of militants.

Alaa Al Sadi, who lives in the Jenin camp, said soldiers who came to his home searching for guns smashed his television before taking him blindfolded into detention at an army compound outside the city for about 14 hours, along with hundreds of other people.

The soldiers found no guns but demolished his family home and accused him of being a member of Hamas, telling him he should leave the West Bank and move to Lebanon or Syria, Al Sadi, 44, said in an interview. He denied any links to the Gaza-based Islamist militant group.

The Israeli military did not respond to a request for comment about Alaa Al Sadi’s account.

The majority of the people taken into detention earlier in the raid have since been released, the Palestinian Prisoner’s Club, an advocacy group, said in a statement. The Israeli army said 60 wanted suspects were transferred to security forces for further questioning.
