ABU DHABI -- Florian Wellbrock took victory in the men's 1,500m freestyle by breaking the world record on Tuesday as the 15th FINA World Swimming Championships (25m) concluded here with four world records.

Earlier at the Abu Dhabi Aquatics Festival, held in parallel with the Short-course Worlds, Wellbrock won the 10km open water swim.

The 24-year-old German was even more dominant in the pool, clinching the 1,500m freestyle title in 14:06.88, more than four seconds faster than second-placed Tunisian Ahmed Hafnaoui and 1.18 second faster than the world record held by Italian Gregorio Paltrinieri since 2015.

The long-distance specialist had made the same achievement two years ago by bagging home both the 1,500m freestyle and 10km open water title at the Long-course Worlds in Gwangju, South Korea.

At the Tokyo Olympic Games this summer, Wellbrock triumphed in the 10km open water event and finished third in the 1,500m freestyle final.
