A U.N. official is warning the Security Council that Israel's plans for further settlements in east Jerusalem threaten the viability of the future Palestinian state.

The council was meeting in emergency session Wednesday at the request of council member Jordan on behalf of the Palestinians.

Tensions have soared between Arabs and Jews over Israel's plans to build about 1,000 housing units in east Jerusalem, the part of the city the Palestinians demand for their future state.

U.N. political chief Jeffrey Feltman says the settlements, if pursued, would raise "grave doubts" about Israel's plans for a durable peace solution with the Palestinians. He urges both sides to commit to "meaningful negotiations."

Israel's ambassador says his country is doing everything possible to minimize tensions. The Palestinian ambassador says Israel isn't listening.
