 Hello, I'm Roisin Hastie with the BBC News. Anti-government demonstrators have returned to the streets of the Kenyan capital, Nairobi, in defiance of warnings by the authorities. In the past few minutes, police have fired tear gas to disperse crowds. The protesters had already forced President William Ruto to abandon his deeply unpopular finance bill. More than 20 people were killed by police on Tuesday. This protester, who did not want to be named, said Mr Ruto's concessions didn't go far enough.
