I don't think they're chanting "USA". You can hear something similar in the first video but it definitely isn't USA.
Interestingly, in the first video there's a group chanting and dancing underneath a large entrance. It looks like they're holding up Bibles and some posters with "Jesus" written on them.
It would be interesting to find out the real story of what was going on here and what is going on in the Ivory Coast. I have a feeling that we'll find the Muslimes are behind the trouble. They bring death, destruction, and despair with them everywhere they go.
The french are accused by the Ivory Coast government of protecting the muslim rebels.
It is very interesting that no guns are visible in the crowd. Also, they only burn one vehicle -- a UN truck.
"I don't think they're chanting "USA"..."
I'll say it again...I saw a news report several days ago on Australian TV that showed the protesters walking calmly along a street, carrying signs that said USA PLEASE HELP US!
The people looked just the same as those in the beginning of the video. Mixed ages, young and old, men, women and children. And not one of them was armed!
