Cécile Djunga has been presenting the weather on Belgian public TV for a year, and after being subjected to a stream of racist comments she has decided to fight back.
In a five-minute appeal on Facebook, Ms Djunga says one viewer rang into work to complain she was “too black and all people could see were my clothes”.
The video went viral, viewed by 700,000 people.
Her employer, RTBF, has given full backing to its presenter.
Its head, Jean-Paul Philippot, told Belgian radio on Thursday that Ms Djunga had passed on a string of messages she had received in recent months and had not reacted to them.
“There’s no place for this torrent of mud in Belgium,” he said. “Racism is a crime, punishable by law.”
