Botswana's Makwala barred from stadium

Botswana's Isaac Makwala was refused entry to the London Stadium, after earlier being withdrawn from the night's 400 meters final at the World Championships after falling victim to an outbreak of sickness that has hit scores of competitors.

The 30-year-old, who was considered one of the main challengers to gold medalist Wayde van Niekerk and is a national icon, also been ordered to withdraw from Monday's opening round of the 200m.

"I arrived at the stadium today ready to run but I found a trap set there ... and was denied entrance (Government order by the way not IAAF)," he said later in a message to his fans on Facebook.

In the second statement, the IAAF said Makwala had been diagnosed with an "infectious disease" following an examination by a doctor in the warm-up medical center on Monday and said the Botswana team had been informed.

Competition organizers said on Monday that the illnesses were a result of gastroenteritis, but public health officials said on Tuesday that laboratory tests had confirmed two cases of norovirus among approximately 30 victims.
