Jewish settlers torched a rooftop enclosure of a Palestinian man's home in the West Bank city of Hebron on Saturday, reuters quoted a Palestinian police spokesman as saying. The United Nations as well as Palestinian and Israeli officials have condemned violence by settlers since tensions rose on Thursday in the occupied territory after Israel's eviction of settler families from a palestinian house in Hebron. Nidal Awawi told Reuters a room he had built on his roof was blackened and destroyed by a fire set off before dawn. There were no casualties, he said. A spokesman for Palestinian police, Ramadan Awad, blamed the arson on Jewish settlers he said were spotted fleeing the scene as flames engulfed the building. The U.N. Middle East envoy, Robert Serry, demanded in a statement on Friday that Israel put "an immediate end to the settler attacks" after settlers shot and wounded three Palestinians in a rampage the day beforehand in Hebron.
