Irish Paralympic stars Jason Smyth and Michael McKillop both claimed gold medals at the IPC World Athletics Championships in Doha.
Smyth won his fifth world title by retaining his T13 100m title in a time of 10.62 seconds.
Smyth’s room-mate McKillop retained the T38 800m title 90 minutes later in a season’s best time of 2:01.31.
McKillop will be favourite to win a sixth IPC world gold medal when he defends his T38 1500m title next Friday.
His latest victory maintains an unbeaten record in Paralympic competition which stretches back to his 1500m silver medal at the 2006 IPC World Championships in Assen.
