German police have detained about 400 left-wing demonstrators who were trying to prevent people entering a right-wing party conference in Stuttgart.

About 1,000 officers were involved in the operation to keep the two sides apart, as the protesters blocked roads, burned tyres and threw firecrackers.

The Alternative fur Deutschland (AfD) party is expected to re-brand itself as openly anti-Islamic during the meeting.

The AfD wants to ban the burqa and outlaw minarets in Germany.
