Lithuania closed Vilnius ​airport on Sunday and NATO ‌summoned at least one fighter jet in response to a possible sighting ​of a drone in ​Lithuanian airspace, the country's National Crisis ⁠Management Centre said.

The air alert ​was lifted, and the airport reopened ​after about an hour, the centre said.

A jet was summoned from Siauliai in ​northern Lithuania, the centre said, ​where the Italian air force is currently ‌based ⁠as part of the NATO Baltic Air Defence mission.

Countries along NATO's eastern edge have reported a ​series of ​drones ⁠straying into their airspace linked to the conflict stemming ​from Russia's 2022 full-scale invasion of Ukraine.

The Vilnius marathon, which was taking place in the ⁠capital, ​was not interrupted, the ​organisers told Reuters.
