Iran and its proxy terrorist militias have issued targeted threats against universities in Lebanon, and the State Department has warned Americans to get out now while commercial flights are still available, U.S. officials said.

Officials said Iran has "specifically threatened" American universities across the Middle East.

The U.S. Embassy in Beirut described the security situation in Lebanon as "volatile and unpredictable."

"Airstrikes, drones and rocket attacks occur throughout the country, especially in the south, the Beqaa, and parts of Beirut," officials wrote in a security alert.

Commercial flights are being offered by Middle East Airlines, operating out of Beirut Rafic Hariri airport. 

Officials said Americans should strongly consider departing on one of the flights "if they believe it is safe to do so."

The U.S. Embassy in Beirut is providing limited passport services on an emergency basis to U.S. citizens.

All routine consular services, including visa operations, are suspended until further notice.

Those who have plans to travel to Lebanon should cancel them, officials said.
