Russia says it repelled drone attack on Crimea

In a social media post, Russian statesman and mayor of Sevastopol Mikhail Razvozhayev said "no facilities in the city were hit."

"The situation is calm and under control. All operational teams are on standby," he said.

Russian state news agency TASS reported that ferries and boats have been temporarily blocked from accessing the bay.

CNN cannot independently confirm or verify Razvozhayev's claim. There has also been no acknowledgment of the incident from Ukraine's side.

Sevastopol, along with the rest of Crimea, is internationally recognized as being part of Ukraine. It is the largest city in the peninsula and has been an important port and a major naval base for Russia's Black Sea Fleet.

Ukrainian President Volodymyr Zelensky has vowed to "liberate" all of the country's territory including Crimea, which has been under Russian occupation since 2014.

The news comes amid the death of a Russian journalist working for a major Kremlin-backed media, who was killed in a shooting accident at a military training ground in Crimea on Friday, Russian officials and state media said.

This is a developing story. More to come.
