Police clashed Saturday with activists who took to the streets of Berlin to shout down anti-migrant marchers of the populist-nationalist Alternative for Germany (AfD). At least 10 supporters of the migrants were arrested, an AFP journalist at the scene said. Police said an officer was lightly wounded in the brawl. Police said some 3,500 people turned out for the anti-migrant protest, which gathered under the banner "Asylum Has Its Limits - Red Card for Merkel". Organisers had expected a turnout of up to 5,000.
