Woolwich attack: Youths gather amid tension
Police have been dispersing small groups of youths in Woolwich town centre after a man was killed in a suspected terrorist attack there.
Two suspects were shot and wounded by police after a machete assault. There are unconfirmed reports that the dead man was a soldier.
Footage has since emerged of a man with bloodied hands shouting political statements near the scene.
The BBC's Susana Mendonca says that some of the protesters had English Defence League (EDL) banners.
