At least six people have been injured after bottles and fireworks were thrown during a far-right protest in the eastern German city of Chemnitz.
Police in the city acknowledged it had not mobilised enough officers for the demonstration on Monday night, which erupted into clashes between neo-Nazis and left-wing counter-protesters, according to the dpa agency.
The far-right protest was sparked by the death of a 35-year-old German man on Sunday following a violent altercation with several other men.
Two other men were injured.
A 22-year-old Syrian and a 21 year-old Iraqi have been arrested on suspicion of manslaughter.
Footage showed far-right protesters trying to break through police lines, performing Nazi salutes and chanting “the national resistance is marching here”.
