Anti-G20 protesters have rioted for a second night through the streets of Hamburg.
Anti-globalisation activists set up street barricades, looted supermarkets and attacked police with slingshots and petrol bombs as the city hosts the Group of 20 leaders.
Police described the riots as extremely violent in the early hours of Saturday in the city’s Schanzenviertel neighbourhood.
Hundreds of officers went into buildings to arrest rioters while being attacked with iron rods and Molotov cocktails thrown from the roofs.
Thirteen activists were arrested when special units stormed one building.
Around 500 people looted a supermarket in the neighbourhood as well as smaller shops.
Cars were also torched and street fires were lit as activists built barricades with garbage cans and bikes.
World leaders will come together later on Saturday to tackle issues including terrorism, climate change and trade, in the final day of the G20 summit.
