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, aged from 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.
