Paralympic champions Jason Smyth and Michael McKillop have both won gold medals at the IPC Athletics World Championships in Lyon.

McKillop took first place in the T37 800m race, setting a new world record of 1:57:19.

And Smyth followed up with victory in the T13 200m to secure Ireland's second gold medal of the day.

McKillop was first into action this afternoon in the searing heat at the Parilly Stadium.

Starting from lane eight, the Newtonabbey man took the pace on from the start and was clear with Australia's Brad Scott and Hafid Aharak from Mor after 200m.

From the bell, McKillop was 10 metres clear, where he stretched it it out to come home in a new world record of 1:57.19.

McKillop said: "I was delighted to win and look forward to the 1500m. He's (father and coach) a phenomenal guy, who I can't thank enough. I wouldn't be where I am today without the support he and my mother give me."

Smyth was dominant throughout the 200m race and was clear of the field within 60 metres.

From lane five he powered home to match his world record time of 21.05.

Namibia's Nambala Johannes finished second in a time of 21.59 with the bronze going to Jonathan Ntutu of South Africa in 22.09.

Smyth was delighted to retain the title he last won in 2006 after missing out the 2011 world championships due to injury.

He said: "It's always nice to get records but at the end of the day I'm here to try and win medals so I'm delighted to have achieved that. I'm looking forward to the 100m now later in the week and am confident I can deliver another top performance."

Earlier, Catherine O’Neill finished fifth in the women’s F51-53 discus final, Orla Barry from Cork was a very credible eighth in the women’s F55-57 shot put final and Heather Jameson ran a season’s best in the T37 womens 200m semi-final but failed to make the final.

Monday will be a quiet day for the Irish team with John McCarthy the only athlete in action. The Dunmanway man takes to the track in the T51 men’s 100m wheelchair racing final at 5:27pm.
