The U.S. government has ceased all security assistance to the Palestinian Authority for training and equipment starting today, a U.S. embassy official told me.

Why it matters: The move coincides with the new anti-terrorism clarification law (ATCA) going into effect. The official said the U.S. security coordinator and his team will continue to conduct a security cooperation-only mission.

Between the lines: U.S. aid to Palestinian security forces was supposed to be $60 million for 2019.

An Israeli security official tells me Israel and the Trump administration are still trying to find a solution that will allow the renewal of U.S. aid to the Palestinian security forces.

The official added: "The cessation of U.S. security assistance will harm the ability of Palestinian security forces to function and could harm security coordination with Israel and create tensions on the ground."

Background: The Anti-Terrorism Clarification Act (ATCA) forces foreign organizations to be subject to the jurisdiction of U.S. courts if they accept certain forms of assistance from the U.S. government. It was signed by President Trump last October with the intention of ensuring the Palestinian Authority pays compensation to terror victims who won civil suits against the PLO in U.S. courts.
