The United States ambassador to Israel advised Americans to leave through Egypt’s Sinai Peninsula as tensions escalate. Ambassador Mike Huckabee said the embassy was receiving numerous evacuation requests while staff remained sheltered in place, according to AP.

In a social media post early Tuesday, Huckabee warned there were “very limited options” for departure. He said it was unclear when Ben Gurion Airport in Tel Aviv would reopen.

He recommended that Americans travel by bus to Egypt’s southern Sinai resorts, including Sharm el-Sheikh and Taba, describing that route as the best available option, AP wrote
