F-16 fighter jets intercepted two aircraft after they entered temporarily restricted airspace near the Florida club where President Barack Obama was spending the long President’s Day weekend.

In a statement on its Facebook page, NORAD said two F-16s were sent to deal with a Lancair 320 aircraft “that was not in communications with air controllers … near Port St. Lucie,” Fla., at 5:10 p.m. Sunday.

“Following the intercept, the … aircraft was escorted out of the [area] and allowed to continue on," it added.

NORAD also said in another Facebook posting that a Cessna was caught inside the off-limits zone at about 9:30 a.m. ET Saturday.

“Following the intercept, the aircraft departed the [restricted area] and landed at Okeechobee Airport where it was met by local authorities,” the statement said.

Obama is taking three days off in Florida while Michelle Obama and daughters Sasha and Malia are in Colorado on a skiing trip.

He is staying at the Floridian, described by The Associated Press as “an exclusive and secluded yacht and golf club on the state's Treasure Coast.”

On Sunday, the president played a round of golf with Tiger Woods at the club.

An F-16 fighter jet went missing Monday after losing connection with its base in Italy around 8 p.m. local time, the U.S. Air Force said in a statement.

Pentagon officials confirm the plane, out on night operations training, is down in the Adriatic Sea, the body of water that separates the Italian peninsula from Croatia and Albania. The plane was assigned to the 31st Fighter Wing at Aviano Air Base in Italy.

The pilot is missing, according to Pentagon officials.

Search efforts are underway, the Air Force said.
