France's U.N. ambassador is warning the Trump administration ahead of the release of its long-awaited Israeli-Palestinian peace plan that any attempt to sidestep a two-state solution and other internationally agreed criteria "will be doomed to failure."

Francois Delattre said that 25 years after the Oslo Accords started the peace process, "there might be a temptation to turn one's back on the agreed framework."

But he warned that pursuing a unilateral path "cannot lead to peace in the region" and "would stoke tensions to unsustainable levels."

His comments to the Security Council on Tuesday reflected growing uneasiness in the international community about the U.S. plan, expected after Israeli elections April 9.

As South Africa's U.N. Ambassador Jerry Matjila said Wednesday, "we cannot outsource the Middle East peace plan to Americans only."
