Kiss enjoyed a successful return to the venue where he won World Championships gold last year as he topped the podium in the KL1 men's 200 metres event.

The Hungarian clocked 52.12sec to edge out France's Remy Boulle, while bronze went to Kiss' team mate Róbert Suba.

Paralympic silver medallist Swoboda claimed two victories in the Hungarian city as he won both the VL3 and KL2 men's 200m races.

The Austrian triumphed in the VL3 in a time of 56.78, just 0.16 clear of Russian Egor Firsov in second place.

Eddie Potdevin of France did enough for bronze having completed the course in 57.75.

Swoboda, who clinched six world titles in a row from 2010 to 2016, returned in the afternoon to win the KL2 event in 47.76.

His victory was much more comfortable than in the earlier race as András Rozbora of Hungary was 3.23 adrift in silver-medal position.

Csaba Rescsik added to the Hungarian medal haul by taking bronze in 54.43.

"It’s been a tough year, so I’m very happy to be here - it’s nice to be with other athletes again," Swoboda said.

"I was really surprised to win, because with the Russian and the French there were two heavy-hitters here. 

"So to come out on top was really nice. 

"I think I was really lucky because I think the conditions helped me a lot."

Russia were the dominant nation in windy conditions on day one as they earned seven golds, including for Nadezda Andreeva in the women's KL2 final, Alexandra Dupik in the women’s KL1 category and Larisa Volik in the women's VL3 event.

Action in Szeged is due to continue tomorrow.
