Jong, generally considered a sprinter and very much a novice in the long jump, registered 5.21 metres at the French capital's Stade Sébastien Charléty.

Among the other long jump winners were Germany's Leon Schaefer and the United States' Roderick Townsend-Roberts.

Schaefer came out on top in the men's T62-64 event with 6.60m, beating Denmark's Daniel Wagner by 0.02m.

Townsend-Roberts prevailed in the men's T42-47 competition with 7.10m.

Japan's Hajimu Ashida was runner-up with 6.87m, while Indonesia's Setiyo Budihartanto came third with 6.84m.

On the track, Para-athletics season debutant Salum Kashafali of Norway completed the men's T11-12 sprint double with a time of 22.30sec in the 200m ranking time races.

Double Rio 2016 Paralympic gold medallist Charl du Toit of South Africa was pushed all the way in the men's 200m T35/37 time races.

He crossed the line in 23.71 to finish ahead of Indonesia's Sapto Yogo Purnomo in 23.84 and Poland's Michal Kotkowski in 23.87.

Tunisia's Walid Ktila added the men's 800m wheelchair T33/34 title to his 400m and 100m crowns with a time of 1:42.62.

Thailand's Chaiwat Rattana came second in 1:50.71, while Great Britain's Jamie Edwards ranked third in 1:57.27.

"I am happy, I feel strong," Ktila said.

"The 800m is hard, tough on the muscles, but I am tough. 

"I can win more gold medals in Dubai (at the 2019 World Para Athletics Championships from November 7 to 15)."
