Polish Jews mark Polish tragedy Polish Jews held a service to mark a roof collapse that killed nearly 70 Poles. Last week’s service at Warsaw’s Nozyk Synagogue commemorated the Jan. 28 collapse in Katowice that killed 67 people. Some 200 people attended the service, as did Israel’s ambassador to Poland, David Peleg. The Union of Jewish Religious Communities of Poland and the Polish Union of Jewish Students sponsored the event.
