Excerpt:
German riot police on Saturday briefly detained some 500 protesters as clashes erupted outside a meeting of the right-wing populist AfD party, which is set to adopt an anti-Islamic manifesto amid a rise in European anti-migrant groups.
Left-wing demonstrators burned tyres and threw firecrackers as they tried to disrupt the start of the Alternative for Germany (AfD) party's weekend congress in the western city of Stuttgart.
The AfD gathering comes a week after the far-right Freedom Party's Norbert Hofer sent shock waves through Austria's political establishment by winning the first round of a presidential ballot.
