WASHINGTON (AP) — The Trump administration has approved a massive new series of arms sales to Israel totaling $6.67 billion and to Saudi Arabia worth $9 billion.

The State Department announced the sales to America’s allies in the Middle East late Friday as tensions rise in the region over the possibility of U.S. military strikes on Iran. They were made public after the department notified Congress of its approval of the sales earlier Friday.

The sales also come as President Donald Trump pushes ahead with his ceasefire plan for Gaza that is intended to end the Israel-Hamas conflict and reconstruct the Palestinian territory after two years of war left it devastated, with tens of thousands dead.

While the ceasefire has largely held, big challenges await in its next phases, including the deployment of an international security force to supervise the deal and the difficult process of disarming Hamas.

The Saudi sale is for 730 Patriot missiles and related equipment that “will support the foreign policy and national security objectives of the United States by improving the security of a Major non-NATO Ally that is a force for political stability and economic progress in the Gulf Region,” the department said.

“This enhanced capability will protect land forces of Saudi Arabia, the United States, and local allies and will significantly improve Saudi Arabia’s contribution” to the integrated air and missile defense system in the region, it said.
