Ultra-Orthodox Jews stand near a fire as they burn leaven in the Mea Shearim neighbourhood of Jerusalem, ahead of the Jewish holiday of Passover, April 6, 2012. Passover commemorates the flight of Jews from ancient Egypt, as described in the Exodus chapter of the Bible. According to the account, the Jews did not have time to prepare leavened bread before fleeing to the promised land. REUTERS/Ronen Zvulun (JERUSALEM - Tags: RELIGION)
