Israel is to build hundreds of new homes in the Adam settlement in the occupied West Bank where a Palestinian stabbed three Israelis, one fatally, Defense Minister Avigdor Lieberman said Friday. Lieberman announced on Twitter 400 new housing units in the settlement that lies north of Jerusalem. The Palestinian attacker infiltrated into the settlement on Thursday evening by climbing a wall, the Israeli army said. He stabbed three people seemingly at random before being shot dead. The army named the man who died as Yotam Ovadia, 31. A 58-year-old victim was said to be seriously wounded but stable while the third victim was lightly injured. The attacker was later identified by official Palestinian media as Mohammed Dar Youssef, 17, from the village of Kobar. The Israeli army said Friday it had raided the village, questioned a number of his family members and suspended their work permits. During the raid on Friday morning, clashes broke out between young Palestinians and soldiers firing tear gas. "The rioters hurled large rocks and firebombs and rolled burning tires at (Israeli) troops, who responded with riot dispersal means," an army statement said. The clashes were over by mid-morning Friday, an AFP photographer said, though the army had established a checkpoint at the edge of the village. Official Palestinian news agency Wafa said three people were arrested. The army added it was "reinforcing the defense" of Adam and other settlements. All Israeli settlement construction in the occupied West Bank is considered illegal by the international community.
