The U.S. on Saturday called on its citizens not to travel to Lebanon and northern parts of Israel, citing “high tensions” in the region, Anadolu reports.

“Due to high tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation,” the U.S. Embassy in Beirut said in a statement.

The U.S. Embassy in Jerusalem also issued a similar warning, stating that Americans “should not travel to Gaza, Northern Israel, and the Egyptian border except for the Taba crossing, and reconsider travel to/through the Middle East.”

The developments come amid heightened tensions in the Middle East, where the U.S. and Iran exchange attacks despite a Pakistan-brokered memorandum of understanding signed in June to end their war and reach a lasting peace agreement.
