UNITED NATIONS - A senior UN envoy Thursday called Israels reported plan to develop new housing units in East Jerusalem a provocative action that undermines international efforts to foster peace talks between it and the Palestinians. Voicing alarm, UN Special Coordinator for the ME Peace Process Robert Serry noted that the Quartet, the diplomatic group comprising the UN, the European Union, Russia and the US that seeks a peace based on two states, Israel and Palestine, living side by side, already condemned the plan when its initial planning stage was announced last year. If confirmed, this provocative action undermines ongoing efforts by the international community to bring the parties back to negotiations, he said.
