A Su-30 fighter jet crashed during a training flight on Saturday in Russia's Kaliningrad region, killing the two pilots on board, RIA news agency quoted the Defense Ministry as saying.
"The Su-30 aircraft crashed in a deserted area. The flight was being carried out without ammunition. The crew of the aircraft died," the ministry said in a statement cited by RIA.
It said the likely cause of the crash was a technical malfunction but gave no further information.
Kaliningrad is a Russian exclave sandwiched between Poland and Lithuania, both NATO member states, on the Baltic Sea.
Ukrainian strikes on Kerch Bridge continue
Russia's Defense Ministry said on Saturday that Ukraine had tried unsuccessfully to strike the Crimean Bridge across the Kerch Strait with S-200 rockets, but that no damage or casualties had been caused.
The 12-mile (19-km) bridge, which links Russian-annexed Crimea to Russia, has come under repeated attack from Ukrainian forces since Moscow launched a full-scale invasion of Ukraine on Feb. 24, 2022.
"The Ukrainian missile was detected in a timely manner and was intercepted in the air by Russian air defense systems. No damage or casualties were reported," the ministry said in a statement.
In a statement posted earlier on the Telegram messaging app, Russian-installed Crimea governor Sergei Aksyonov said two rockets had been downed by anti-aircraft defenses near the bridge. He also said the bridge was undamaged.
Footage circulating on Russian social media on Saturday appeared to show the bridge wreathed in smoke. Reuters could not verify the footage. Interfax news agency reported that the bridge was briefly shut to traffic but that it later reopened.
Separately, Russian forces destroyed 20 Ukrainian drones launched onto the Crimean Peninsula earlier on Saturday, Russia's Defense Ministry said.
There were no casualties and no damage as a result of the drone attacks, the ministry said on Telegram. It said 14 drones were destroyed by air defense systems and six were suppressed by electronic warfare.
Reuters could not independently verify the report.

It was not immediately clear what was targeted in those reported attacks on the Black Sea peninsula, which Russia annexed from Ukraine in 2014.
Ukrainian drone attacks are increasing
Drone attacks on Russian-controlled territories in Ukraine and deep inside Russia have increased since a drone was destroyed over the Kremlin in early May.
Ukraine almost never publicly claims responsibility for the attacks but has said destroying Russia's military infrastructure is crucial for Kyiv's counteroffensive.
The Crimean Bridge was badly damaged last October in a powerful blast that Russian officials said was caused by a truck that blew up while crossing the bridge, killing three people.
Ukraine's SBU domestic intelligence agency later claimed responsibility for the sabotage operation.
The bridge, which is the only direct link between the transport network of Russia and the peninsula, was a flagship project for Russian President Vladimir Putin, who opened it for road traffic to much fanfare by driving a truck across in 2018.
