Jason Smyth says he "keeps wondering when the fairytale is going to end" after he wins a fifth Paralympic gold medal as he defends his T13 100m title in Rio.
The Northern Irishman clocked 10.64 seconds as he finished 0.14 ahead of Namibia's Johannes Nambala.
Ireland athlete Smyth's gold came after the triumph by another Northern Irish competitor Bethany Firth who won a swimming gold for Britain on Thursday.
"It's been incredible," added the County Londonderry man.
"It's my third consecutive Paralympic Games and fifth gold medal. To be honest, it's a little bit like a fairytale.
