Senior PLO official Saeb Erekat  on Wednesday condemned Israel's approval of 58 new housing units in the East Jerusalem  settlement of Pisgat Zeev.An Israeli municipality committee in Jerusalem approved the construction on Wednesday in a majority vote."Our position is clear and in line with international law: all Israeli settlements in Palestine are illegal ," Erekat said."Settlement construction in occupied East Jerusalem, Ariel and Kiryat Arba is illegal  and undermines the prospects of a negotiated two-state solution. If Israel is serious about peace, they must cease all settlement activities."The international community must take concrete steps against all Israeli settlements and make Israel pay the price  for its "institutionalized defiance of international law and UN resolutions."Peace talks between Israelis and Palestinians were relaunched in July under the auspices of the United States after nearly three years of impasse.Israel's government has announced the construction of thousands of housing units in illegal settlements  since peace talks began.More than 500,000 Israeli settlers live in settlements across the West Bank and East Jerusalem, in contravention of international law.
