Britain said on Tuesday there was "no indication" that a Ukrainian warship and a stock of anti-ship missiles were at the dock-side in Odesa port on Sunday, after Russia earlier said it had destroyed those targets with high-precision missiles.

"Russia will continue to prioritize efforts to degrade and destroy Ukraine's anti-ship capability. However, Russia's targeting processes are highly likely routinely undermined by dated intelligence, poor planning, and a top-down approach to operations," the British Ministry of Defence said in a regular intelligence update.

Ukrainian military has said two Kalibr missiles fired from Russian warships hit the area of a pumping station at the Odesa port and two others were shot down by air defense forces.
