ACTIVISTS clashed violently with riot cops in Germany setting cars ablaze, looting shops, throwing petrol bombs and trying to gatecrash the convention centre hosting the G20 talks. Hundreds of extra police were drafted in to the streets of Hamburg in a bid to keep the increasingly violent protests by anti-globalisation rioters under control. But as these shocking images show the port’s streets were once again turned into a burning battleground. Around 200 police officers were injured, dozens of activists had to be taken to the hospital and more than 70 protesters were detained.
