Former Brazilian president Jair Bolsonaro has been taken to a hospital after feeling sick, his son Flavio Bolsonaro wrote in an X/Twitter post late Tuesday night.

"President Bolsonaro felt unwell a short while ago, with a severe bout of hiccups, vomiting, and low blood pressure," the post read.

"I ask for everyone's prayers so that it is nothing serious."

This is a developing story.
