Belgian Prime Minister Alexander De Croo fell from a bicycle and briefly lost consciousness but hospital tests revealed no lasting effects, national news agency Belga reported.
The incident happened when Mr De Croo, 47, was on a bike ride with his son yesterday afternoon near his home in the Flanders region, according to Belga, citing the prime minister's office.
Mr De Croo lost consciousness for a few moments and was taken to hospital for checks, Belga reported.
In a video message posted on social media, Mr De Croo said he was now back home.
"Fortunately, I was wearing a helmet and my son called the emergency services," said Mr De Croo, who thanked medical staff for looking after him and well-wishers for getting in touch.
"Sport is good for your health. But sometimes you have to be a little careful," he said.
The accident was not expected to affect the premier's schedule for the coming week, Belga said.
