UNITED NATIONS (AFP) - UN Secretary General Ban Ki-moon insisted Wednesday that Israel's refusal to halt the colonisation of Palestinian territories must not end Middle East peace talks, his spokesman said. The Secretary General takes note with regret that Israel will not heed the united call of the international community' to halt construction in Palestinian territories, UN spokesman Martin Nesirky said in a statement. Ban made a new plea for Israel to meet its obligations under the road map to peace drawn up by the diplomatic Quartet on the Middle Eastthe United States, Russia, European Union and United Nationsand freeze all settlement activity. In spite of this setback, the secretary general believes it is more important than ever to promote a negotiated end-game for a two-state solution, said the spokesman. He is encouraged that the United States has indicated its determination to continue its efforts in this direction and he urges the full cooperation of the parties towards that end. The US government said Wednesday it still hoped for an Israeli-Palestinian peace deal by next August despite Israels settlements decision. Palestinians stopped negotiating with Israel after the Israeli government ended a 10 month building freeze. Ban hoped for talks among Quartet members in coming days, the spokesman said.
