the world. this had been a peaceful demonstration up until now. our frederick pleitgen was on the streets there. told us about 10,000 people, he thinks. it could have grown on the streets there. then something set this off. we saw some skirmishes back and forth right there and then the water being shot there. again, this has been going on for some time. this follows the meeting between president trump and german chancellor angular merkel. we have nod had a readout of that meeting. we do know that meeting has wrapped up and president trump has moved on to other items on this agenda, not even sure how close these meetings are to where these demonstrations are taking place. you can see a large-scale action now by law enforcement moving through the crowd, trying to break them up. trying to break them up and disperse the crowd as best they can. our frederick pleitgen has been out on the streets this whole time. fred, what are you seeing? reporter: yes.
