The United Arab Emirates has signed an agreement with the United States to purchase 50 F-35 jets and up to 18 armed drones, people familiar with the situation told Reuters on Wednesday.

Although the UAE and the United States were working to ink a deal before President Joseph Biden took office on Wednesday, the new president has said he will re-examine the agreements.

The UAE, one of Washington’s closest Middle East allies, has long expressed interest in acquiring the stealthy F-35 jets made by Lockheed Martin and was promised a chance to buy them in a side deal when it agreed to normalize relations with Israel last August.

The U.S. State Department and the UAE Embassy in Washington did not immediately respond to requests for comment.
