Wallström urges Russia to "stop provocative behaviour" over Ukraine

Sweden's foreign minister expressed worry over an incident in the Kerch Strait that saw Russian warships seized three Ukrainian naval vessels on Sunday.

The narrow waterway provides access from the Black Sea to the Sea of Azov near Crimea, and the episode represents a rise in tensions between the two countries.

Moscow claims the Ukrainian ships illegally entered Russian water and were planning an attack. Russia is not releasing the ships, keeping them docked in a nearby harbor.

Ukraine, for their part, says Russia broke the agreement which allows both countries territorial rights over the waterway, which is the only way out of the sea.
