That's where a police officer shot and killed 18 year old Michael Brown Saturday.
Wednesday night's protest started as a peaceful march, but CBS affiliate KMOV reports tear gas was fired into a crowd after protestors threw rocks and Molotov cocktails at police.
Police arrested at least 10 people, including a St. Louis alderman and two reporters. One police officer suffered a broken ankle.
Governor Nixon issued a statement overnight that said:
"The worsening situation in Ferguson is deeply troubling, and does not represent who we are as Missourians or as Americans. While we all respect the solemn responsibility of our law enforcement officers to protect the public, we must also safeguard the rights of Missourians to peaceably assemble and the rights of the press to report on matters of public concern.
"I have been closely monitoring the situation and will continue to be in communication with local leaders, and I will be in north St. Louis County tomorrow. As Governor, I am committed to ensuring the pain of last weekend's tragedy does not continue to be compounded by this ongoing crisis. Once again, I ask that members of the community demonstrate patience and calm while the investigation continues, and I urge law enforcement agencies to keep the peace and respect the rights of residents and the press during this difficult time."
