A peaceful boom, set off by a Muslim and a Jew, echoed through Jerusalem's Old City Sunday night, ending the daily fast during the Muslim Ramadan holy month.

Jerusalem Mayor Uri Lupolianski joined Rajai Yehye Sandouka in setting off the ceremonial shot. Sandouka is the latest in a long line of family members, dating back to the Ottoman rule in the early 20th century, who have fired the traditional cannon.

But Sandouka said the tradition might be in jeopardy. He said Israeli officials have ordered him to undergo explosives training before next Ramadan, or he would be barred from lighting the fuse.
