Welcome back to our continuing live coverage of Russia’s war on Ukraine. This is Adam Fulton and here’s an overview of the latest developments.

Russia’s defence ministry said early on Saturday that its forces had destroyed an unmanned Ukrainian boat being used in an attempt to attack the bridge linking the Crimean peninsula to the Russian mainland.

The ministry said the attempt was made with the “half-loaded” boat late on Friday but it was seen and destroyed, as were three naval drones, off the Black Sea coast.

There was no immediate comment from Ukrainian officials. The bridge has come under repeated attack during Russia’s invasion of Ukraine.

Meanwhile, Ukrainian forces have made “notable progress” in their southern offensive over the past three days, a leading US security official has said.

Kyiv said its troops had broken through Russia’s first line of defences in several places.
