Kenyan police fire tear gas grenades at protesters trying to hold a demonstration against police killings of protesters and opposition supporters, in downtown Nairobi, Kenya Thursday, October 19, 2017. Police fired tear gas grenades and rifles in the air to disperse around 20 activists as they were still gathering in Uhuru Park, despite a court order Tuesday that removed the government's ban on demonstrations.
