Cyclist dies after crash in Paralympics race
An Iranian cyclist died after crashing in a road race at the Rio de Janeiro Paralympics
He was Bahman Golbarnezhad, aged 48, the International Paralympics Committee said.
It said he received emergency treatment on the course and was taken to a Rio hospital where he died.
"This is truly heart-breaking news, and the thoughts and condolences of the whole Paralympic Movement are with Bahman's family, friends, and teammates, as well as the whole of the National Paralympic Committee of Iran," IPC President Philip Craven said.
The IPC said it believes this is the first death in a Paralympics.
Golbarnezhad crashed about 10:40am local time on Saturday on a mountainous stretch of the road cycling course. The IPC said he suffered cardiac arrest on the way to the hospital.
The cause of the crash was not clear, and officials said it was being investigated.
"The Paralympic family is united in grief at this horrendous tragedy, which casts a shadow over what have been great Paralympic Games," Mr Craven added.
The Iranian flag was lowered to half-mast in the Paralympic Village, and at the venue where Iran faces Bosnia and Herzegovina in a men's sitting volleyball final on Sunday.
A moment of silence will also be held at Sunday's closing ceremony in Maracana Stadium.
"This is very sad news for sport and for the Paralympic movement." Carlos Nuzman, head of the Rio Olympic organising committee, said.
"Our hearts and prayers are with Bahman's family, his teammates and all the people of Iran."
A Paralympic biography said Golbarnezhad was born in Shiraz, Iran.
He also competed in the London Paralympics but did not win a medal. He was competing in the C4-5 races for athletes with lower limb impairments or amputations.
This was his second race in Rio. On Wednesday, he finished 14th in a time trial.
