VILNIUS, June 13 (Reuters) - Lithuania on Saturday briefly warned residents in its capital of a potential military drone incursion into its airspace, but later said the alert had been triggered by a weather balloon.

The Baltic region remains on high alert after a series of recent airspace violations, in which Ukrainian long-range drones missed targets in Russia and strayed into neighbouring nations.

Lithuania's National Crisis Management Centre said NATO aircraft were briefly summoned on Saturday to intercept the suspect drone, and visually identified it as a weather balloon.
