Police spokeswoman Luba Simmari said detectives closed the premises of the Heritage Committee in the East Jerusalem neighborhood of Wadi Joz, which she accused of being affiliated with Hamas, the Islamist political party which controls the government in the Gaza Strip.
The party runs hundreds of community organizations in the West Bank and Gaza.
“It is the intention of the police to arrest suspects responsible for reopening it,” she told AFP. “It was run by Hamas… Hamas is forbidden to work in East Jerusalem.”
Neighbors said that the two-story building was also used for prayers.
An eyewitness said that police welded its doors shut.
Israel considers Hamas a “terrorist organization” and prohibits any activities run by the party to take place in territory it controls.
The Palestinian Authority is also prohibited from carrying out official activities.
