Russia - still labelled as such by the International Swimming Federation (FINA) despite World Anti-Doping Agency sanctions - trailed 11-13 in the final period, but scored three unanswered goals to defeat the 2016 Olympic runners-up and move top of Group B.

The Russians have three wins and one draw, leaving them in pole position to win the group.

The Dutch hosts also produced a remarkable comeback, recovering from 5-9 down to draw 11-11 with France.

Fewer than three seconds remained when The Netherlands scored their final equaliser, winning the fourth quarter 6-2.

Romania beat Germany 12-7 in the group's other match, eliminating the Germans.

A winner-takes-all game between Romania and France - level on three points - will decide who will be the final team to advance from Group B, with Croatia, Russia and the host nation all through already.

France's goal difference is better than Romania's.

In Group A, already-eliminated Brazil fell 12-8 to Georgia and Montenegro beat Greece 8-4.

With Turkey disqualified because of a coronavirus outbreak, there were only two games played, and Montenegro, Georgia, Greece and Canada are all through to the quarter-finals.

Montenegro - Rio 2016 fourth-place finishers - will top the group if they avoid defeat versus Georgia tomorrow. 

The tournament's top three teams will qualify for this year's Olympic Games in Tokyo.
