France, Germany and Sweden said they will send military personnel and anti-drone systems to Denmark to boost security at this week’s European summits in Copenhagen.

KYIV — The Ukrainian military is sharing with European countries its expertise in fighting Russian drones, sending a mission to Denmark for joint exercises, Ukraine President Volodymyr Zelensky said Tuesday. “Our military has begun deploying a mission in Denmark to disseminate Ukrainian experience in drone defense,” Zelensky said.

Denmark said drones that halted flights at its main airport on Monday were the most serious attack yet on its critical infrastructure and linked them to a series of suspected Russian drone incursions and other disruptions across Europe.

BRUSSELS (AP) — European defense ministers agreed on Friday to develop a “drone wall” along their borders with Russia and Ukraine to better detect, track and intercept drones violating Europe’s airspace.

In response to drone incursions that disrupted air traffic, France, Germany, and Sweden are deploying military personnel and anti-drone systems to Denmark. This move is aimed at safeguarding upcoming European summits in Copenhagen.

It wasn’t immediately clear who was behind the flyover. But Denmark’s prime minister and NATO’s secretary-general said Tuesday that Russian involvement couldn’t be ruled out.

Russian Foreign Minister Sergey Lavrov warned, 'Any aggression against my country will be met with a decisive response.'

A wave of drone incursions across the EU is fuelling uncertainty and testing resilience. While some are linked to Russia, others remain unexplained, highlighting gaps in preparedness and the need for a unified European response.
