JERUSALEM  Palestinian political activists from the Jenin refugee camp in the northern West Bank on Sunday condemned a camp youth orchestra’s performance for Holocaust survivors in Israel last week, and said they were banning the orchestra’s director, an Israeli Arab woman, from entering the camp.

In an unusual, almost surreal encounter, a group of 13 young musicians from the Jenin camp, ages 12 to 17, played Wednesday for about 30 elderly Holocaust survivors at a social club in the Israeli town of Holon, just south of Tel Aviv. The hourlong concert was a central event of Israel’s annual Good Deeds Day, sponsored by an Israeli billionaire.

Adnan al-Hindi, the leader of the camp’s Popular Committee, a grass-roots group representing the Palestine Liberation Organization, said the young musicians had been exploited by the orchestra director, Wafaa Younis, for the purpose of “normalizing” ties with Israel. He said by telephone that the children had been “deceived” and dragged unwittingly into a political situation that “served enemy interests” and aimed to “destroy the Palestinian national spirit in the camp.”

“It was a shock and a surprise to the children and their relatives,” he said, adding that Ms. Younis had told the young musicians’ families only that the trip to Holon was an opportunity for artistic self-expression.
