Dozens of Israeli men were in jail on Friday a day after ultra-Orthodox Jews staged their largest protest in 10 years in support of parents who defied a supreme court ruling on school integration. But 22 mothers of pupils at an ultra-Orthodox girls' school in a West Bank settlement were given a stay of arrest while the court considered a plea to let them stay at home to care for their young families. Settlers' news website Channel 7 and public radio said Judge Edmund Levy decided that the court would reconvene on Sunday to discuss the request. Israeli media said that some of the mothers were pregnant, while others had children with special needs. Ultra-Orthodox families generally have large families, far above the average of the secular Israeli population. "We shall wait for the court's decision before taking any action," police spokesman Micky Rosenfeld told AFP. The media reported that a confrontation with the parents' many supporters would be likely if police sought to arrest the women. Around 100,000 angry ultra-Orthodox Jews rallied in Jerusalem on Thursday in protest at the court's decision to jail a group of parents of European origin, or Ashkenazis, for refusing to send their daughters to a school with Jewish girls whose families originate from Arab countries, known as Sephardis. It was the biggest demonstration by the ultra-Orthodox since February 1999 when at least 250,000 protesters declared their opposition to supreme court rulings challenging the Orthodox establishment's monopoly on marriage, divorce and other religious and social issues.
