U.S. President Donald Trump's administration is discouraging governments around the world from attending a U.N. conference next week on a possible two-state solution between Israel and the Palestinians, according to a U.S. cable seen by Reuters.

The diplomatic demarche, sent on Tuesday, says countries that take "anti-Israel actions" following the conference will be viewed as acting in opposition to U.S. foreign policy interests and could face diplomatic consequences from Washington.

The demarche, which was not previously reported, runs squarely against the diplomacy of two close allies France and Saudi Arabia, who are co-hosting the gathering next week in New York that aims to lay out the parameters for a roadmap to a Palestinian state, while ensuring Israel's security.
