>> Germany is bracing for violent protests and contentious policy discussions at a G20 summit in Hamburg next week at which the host, German Chancellor Angela Merkel, will be trying to forge consensus with other leaders including US President Donald Trump, Russia's Vladimir Putin, and Turkish President Tayyip Erdogan. I'm Noah Barkin, special correspondent for Europe at Reuters in Berlin.
Summits of world leaders like this are usually held in remote locations where protesters can be kept at a distance, but Merkel has decided to hold this summit at a convention center in the middle of Hamburg in order to send a message to other leaders that protests are part of a healthy open democracy.
That has put huge pressure on German police, who will be out in force on the streets of Hamburg. An estimated 20,000 police from all of Germany's 16 states will be there. They're gonna be facing off against tens of thousands of protesters, including up to 8,000 anarchists and left wing extremists who are prepared to use violence, according to the police.
Security officials are also worried about the potential for clashes between supporters of the PKK, the Kurdish military group, and Turkish nationalists who support Erdogan. On the policy front, the hosts Germany are girding for tough discussions with Trump on climate change, trade, and migration. G7 leaders were unable to convince Trump last month, at a meeting in Sicily, to stay in the Paris climate accord.
The Trump administration is threatening punitive trade measures against China and other countries on steel, in the run up to the G20 summit.
