CAIRO (AP) — U.S. Secretary of State Rex Tillerson has arrived in Egypt at the start of a regional tour that coincides with heightened regional tension and unease over the Trump administration's Mideast policies.

His arrival Sunday came one day after Israel carried out a wave of airstrikes in Syria after intercepting an Iranian drone that had infiltrated its airspace and an Israeli F-16 was downed upon its return from Syria. It was the most serious Israeli engagement in Syria since the war there began in 2011.

In Egypt, as well as in Kuwait, Lebanon and Jordan — the tour's other Arab stops — Tillerson will almost certainly hear misgivings about President Donald Trump's recent decision to recognize Jerusalem as Israel's capital.

He visits NATO ally Turkey on the tour's final stop.
