STOCKHOLM — Swedish police detained 28 people Sunday after a group of neo-Nazis attacked an anti-Nazism demonstration in a Stockholm suburb by hurling bottles, torches and firecrackers.

Two people were hospitalized and a policeman was injured in the back after being hit by a heavy object, police spokesman Sven-Erik Olsson said.

Olsson said around 200 people participated in the planned, peaceful demonstration in the suburb of Karrtorp when they were attacked by a smaller group of about 40. Those detained are suspected of rioting and various assault charges.

The demonstration was organized by a local citizen group as a protest against increased neo-Nazi campaigning in the area.

Video footage published by state broadcaster SVT showed families with baby carriages escaping the scene as firecrackers exploded in the middle of the crowd and people were heard screaming. Later, the crowd moved toward the attackers chanting anti-Nazism slogans and forcing them to retreat.

A neo-Nazi group called the Swedish Resistance Movement claimed responsibility for the attack on its website.
