Trump traveled from Riyadh to Tel Aviv in what appears to be an unprecedented direct flight by a U.S. president between those nations, which don’t have diplomatic relations, in a region fraught with tension.

“It’s a direct flight,” Secretary of State Rex Tillerson told reporters traveling with the president aboard Air Force One. Of the hopes for a peace plan between Israel and the Palestinians, Tillerson added, “There’s a moment in time here.”

Speculation of such a flight by Trump into Israel from the Saudi capital has swirled for weeks. The Haaretz newspaper noted that two past sitting U.S. presidents — Richard Nixon and Bill Clinton — had previously flown from Syria into Israel, but none had made the flight directly from Saudi Arabia.
