Israeli Prime Minister Benjamin Netanyahu traveled overnight by a civilian jet to Saudi Arabia reportedly for a secret meeting with the Crown Prince Mohammed bin Salman, which would mark the first known encounter between senior Israeli and Saudi officials.

A Gulfstream IV private jet left Tel Aviv on Sunday at 7:30 p.m. local time and flew directly to the seaside resort town of Neom, according to FlightRadar.

Netanyahu headed back to Israel after two hours on the ground, arriving in Tel Aviv half past midnight.

Israeli chief spy and the head of Mossad, Yossi Cohen, joined for the meeting, which was also attended by U.S. Secretary of State Mike Pompeo.
