Multiple British warplanes have been scrambled out of RAF Akrotiri after the British sovereign base was rocked by a blast.
An explosion was heard near the base late on Sunday night - with a pair of Typhoon fighter jets and a larger Voyager jet sent out as a result.
The Voyager, comparable to a small passenger jet in size, is typically deployed for air-to-air refuelling of fighter jets for longer-range missions.
Flight tracking data showed the planes flying east out of Cyprus - before then disappearing from the radar.
Both the scramble and the blast follow the news that Britain has agreed to a US request to use its military bases to strike Iranian missile sites.
Meanwhile, air traffic control chatter from the eastern Mediterranean appears to indicate "a lot of missiles" between cyprus and Beirut, Lebanon.

As Cyprus sits in the firing line... Hezbollah launches 'projectiles' at Israel
Hezbollah is said to have launched projectiles at Israel this evening, bringing Lebanon into this weekend's conflict for the first time.
The Israeli military said that projectiles launched from Lebanon resulted in sirens sounding in several areas in northern Israel.
Israel and Lebanon agreed to a US-brokered ceasefire in 2024, ending more than a year of fighting between Israel and Lebanese terrorist group Hezbollah that had culminated in Israeli strikes that severely weakened the Iran-backed group.
Hezbollah, an Iranian proxy group, voiced its solidarity with Iran on Saturday but stopped short of saying whether it would get involved.
The Israeli military added in a follow-up statement that it intercepted a launch while other projectiles fell in open areas.

A "security threat" was declared at the base after an explosion was heard just before midnight, telling staff to "return to your homes and stay inside until further notice".
