Britain's most controversial horse race, the Grand National, has sparked outrage after a horse who fell at the first fence has been killed.
Up for Review, who could be seen struggling on the floor on live TV, has been 'put down' - becoming the first horse to die at the Grand National's main race since 2012.
However, two other horses were killed at the racecourse yesterday, during Aintree's three-day 'festival'.
It has been reported ITV, who broadcasted the event live, later showed a replay of the race from the second fence to avoid showing Up for Review's fall.
Celebrity comedian, Ricky Gervais, was one of many high-profile names to speak out about the incident, tweeting: "Why would you gamble with a horse's life for fun? #YouBetTheyDie."
'The race of greedy, callous people'
While animal-rights organization, PETA, said: "At 4.5 miles, the Grand National race is one of the longest and most hazardous in the world – the high-risk factor is what makes it famous.
"This kind of carnage is precisely why people are turning away from horse racing. It's not the race of kings – it's the race of greedy, callous people whose ethics don't comport with our contemporary understanding of horses' sensitivity and intelligence.
"These animals certainly don't deserve to be treated like wind-up toys and then discarded after breakdowns or at the end of their lives. The Grand National is a national disgrace, yet ITV is still broadcasting this unethical spectacle."
A 'Barbaric sport'
ITV Racing posted a video claiming Up for Review had suffered a 'fatal injury' and said: "This is a sport and a race that has a trap door to despair. It does break hearts but it also makes legends."
The tweet received criticism with people dubbing the race as a 'barbaric sport' that 'needs to be banned'.
Since the Grand National first started, 84 horses have been killed. On average, 200 horses die on the racetrack each year.
