Ukraine's military has confirmed that it struck road bridges linking Crimea and Russian-occupied parts of southern Ukraine on Sunday.

The strikes "hit two key routes of communication" for Russia, the Chonhar bridge linking the Kherson region to Crimea and a smaller bridge to the peninsula from the Ukrainian town of Henichesk, the Armed Forces of Ukraine said on Telegram.

Russian-backed authorities and Russian state media had earlier reported that Kyiv was responsible for strikes on the bridges.

The Russian-appointed head of occupied areas in the Kherson region accused Ukraine of using British-supplied Storm Shadow missiles in the attack.
