A Russian SU-24 bomber "violated Swedish airspace" near the strategic Baltic Sea island of Gotland, leaving only after Sweden scrambled a JAS-39 fighter jet, Sweden's military said on Saturday.

"The Swedish air combat command warned the Russian aircraft with a verbal call," the Swedish Armed Forces said. "When this was not heeded and the aircraft did not deviate from its route, it was dismissed from Swedish airspace by a rote JAS-39 Gripen," it said.

Russia has not responded to the claim.
