"stealing" Ukrainian grain, as well as transferring military cargo and fuel. The strikes come as Russian President Vladimir Putin prepares to speak at a major economic event in St Petersburg, and a day after Ukraine's President Zelensky offered face-to-face talks with the Russian leader on ending the war.

Meanwhile, Ukraine has confirmed one of its naval drones exploded off Romania's coast on Friday. No injuries were reported in the blast. It is unclear if the strikes on cargo ships claimed by Kyiv are linked to the deaths of five Azerbaijanis, whom the country's foreign ministry said were killed in drone attacks on ships in the sea. Azerbaijan's foreign ministry said in a statement on Friday that two cargo ships, the Natra and Zirkon, were attacked by drones overnight in the Taganrog Bay area of the Sea of Azov. It did not specify who was behind the attacks and noted that the ships do not belong to Azerbaijan. Russia has blamed Ukraine for the attacks. There was no immediate response from Kyiv. (BBC)
