A Belgian rider in cycling's Tour of Qatar has died in his sleep.
21 year old Frederiek Nolf is believed to have suffered a heart attack.
Organisers have announced today's fifth and penultimate stage will be neutralised, with competitiors riding together from the start to the finish over a shorter distance, as a mark of respect.
Nolf's Topsport team-mates will ride to the start before pulling out of the event.
Yesterday's fourth stage was won by Manx cyclist Mark Cavendish.
