Protesters shouting “no justice, no peace” have disrupted a speech by former FBI director James Comey to university students in Washington DC.
Mr Comey was giving a convocation address at Howard University, a leading historically black college.
It took some 13 minutes before Mr Comey, fired in May as head of the FBI, could be heard by the crowd of 1,500.
From the moment he took the podium he was distracted by chants including “Get out James Comey, you’re not our homie”.
The BBC’s Courtney Subramanian, at Howard University, says protesters have told her that they believe the FBI is an anti-black organisation.
Protesters were yelling expletives about Mr Comey as some demonstrators held “Black Lives Matter” signs just outside the auditorium, she adds.
