Parts of Hamburg are under a blanket of black smoke. G20 protesters in the German city started a huge inferno as the summit of world leaders kicks off.

The summit sessions are now underway with Presidents Vladimir Putin and Donald Trump having shaken hands. But across the city hordes of protesters blocked streets by staging sit-down demonstrations at key intersections.

Reuters reports that streets and bridges leading to the summit were blocked as well as a road used by trucks at Hamburg Port.

Hundreds of left wing anarchists started fires and clashed with police. At least 29 activists are now under arrest and more than 150 policemen are injured.
