Russia began its crossing attempt on 8 May, transporting two companies of soldiers and 30 units of equipment, including tanks, infantry fighting vehicles and armoured personnel carriers, according to Ukrainian information service InformNapalm.

As soon as they crossed, Ukrainian forces destroyed the pontoon bridge in the water, and Russian troops "fell into the trap", it said.

The Russian military suffered heavy losses and many troops tried to escape and swim to the other shore but Ukrainian military immediately opened fire on them, it added.

It said a tank that tried to drive on to the pontoon bridge in the water was fired on and "rolled over" on its side, and others were destroyed, adding that crew members drowned.

More than 70 units of Russian military equipment were lost as a result of the unsuccessful crossing and Ukraine claims more than 1,000 soldiers could have been killed.
