Belgium’s defense minister, Theo Francken, confirmed that multiple unidentified drones were detected flying over a military base in northern Belgium that is reportedly home to U.S. nuclear missiles. The incidents occurred at the Kleine-Brogel Air Base, where Francken stated the drones were tracked but could not be neutralized by a drone jammer.

Francken shared on his X account that the drones were spotted over the weekend and that authorities deployed a helicopter and police vehicles to pursue them. However, the drones evaded capture after traveling several kilometers. “Thanks to the guard for their attention and follow-up,” Francken wrote. He emphasized the need for heightened vigilance to identify the operators behind the surveillance.

The defense minister described the situation as “very concerning” during an interview with RTBF, Belgium’s French-language public broadcaster. He suggested the drones may have been part of a spying operation, noting they lingered over the base for extended periods to monitor strategic assets such as F-16 aircraft and munitions storage.

The U.S. has not announced any plans to resume nuclear weapon detonations, despite President Donald Trump’s recent remarks about testing nuclear capabilities “on an equal basis” with Russia and China. The U.S. military conducts regular missile tests but has not conducted live nuclear warhead detonations since 1992 due to a test ban.
