Kenya's Wilson Bii led a 1-2 finish in the men's 5,000m T11 to bag gold on Day One of the World Para Athletics Grand Prix in Tunis, Tunisia.
Bii clocked 15:56.20 to finish ahead of compatriot Erick Kiptoo who timed 15:59.62 to claim silver.

The event is part of Tokyo Paralympics qualifiers for the quadrennial event set for August 24-September 5.
This is the team's second outing after their first, successful one in Dubai last month, where they bagged a total of 20 medals.
After Tunis, the athletes will shift their attention to other qualifiers in Italy (April 16-18), Beijing (April 23-25), Paris (May 5-7), Nottwil, Switzerland (May 14-16) and Sao Paulo.
The team has been training at the Moi Stadium, Kasarani for close to one month as part of the bubble camp established by Olympics Kenya.
