A number U.S. airlines have promptly suspended flight operation and canceled flights from Israel's airports after Iranian-backed Hamas terrorists invaded areas of southern Israel with rocket barrages Saturday.

According to the U.S. Embassy in Israel, Ben Gurion Airport, the main international airport in Tel Aviv, Israel, remains open, with the embassy warning that "the security situation and staff availability could affect flights."

Following the surprise attack, some flights were diverted to other airports around the globe.

United Airlines said that Flight UA954, which departed from San Francisco International Airport to Tel Aviv, Israel, turned around over Greenland about seven hours into the journey and returned to the California city.

In a statement to Fox News Digital, United Airlines said they had two departures from Tel Aviv today, but future operations "will be suspended" until conditions change in the war-torn country.

"The safety of our customers and crews is our top priority," a United Airlines spokesperson said. "We are closely monitoring the situation, and we are adjusting flight schedules as required."

A Delta Air Lines spokesperson echoed United Airlines sentiments, saying that all Israel flights have been canceled through the weekend.

The Atlanta-based airlines said it will work with the U.S. government as needed to "assist with the repatriation of U.S. citizens who want to return home."

"Delta continues to monitor the situation and is making schedule adjustments accordingly," a Delta Air Lines spokesperson told Fox News Digital. "Customers impacted by canceled flights or who want to change their TLV ticket should check their Delta app, visit Delta.com or call Delta reservations to make adjustments."

American Airlines said it has canceled two of its flights from John F. Kennedy International Airport to Tel Aviv, Oct. 7-8, following the attack. The airlines said that they have issued a travel alert and have suspended operations to and from Israel this weekend.

"We will continue to monitor the situation with safety and security top of mind and will adjust our operation as needed," an American Airlines spokesperson told Fox News Digital. "Customers should visit aa.com or use the American Airlines mobile app to check the status of their flights."
