good to be with you. i'm anne-marie green. the children of ferguson, missouri, were supposed to begin the school year this morning, but classes will not be held as the st. louis suburb braces for what could be another day of violence between police and protesters. last night officers used smoke bombs and tear gas to disperse a group of protestors. some armed with homemade explosives. the protests stemmed from the deadly shooting of michael brown. the unarmed black teenager was shot and killed saturday by a white police officer. on wednesday ferguson's police chief said it will be weeks before the investigation is complete and he addressed the growing racial unrest in the city. >> apparently there's been this undertow that now has bubbled to the surface and it's our first priority to address it, to fix what's wrong. >> the tension could be felt during a peaceful demonstration

on ferguson's streets earlier on wednesday. julian johnson of our st. louis affiliate kmov reports. >> reporter: a protest aimed at peace. >> this is not an isolated incident. this is a buildup to what's been going on in this community for a very long time and the people need to be heard. >> reporter: and it was guns aimed at them. >> return to your vehicles. return to your homes. >> it's sad because that's not the intent of any of this here. >> reporter: the march meant to show support for 18-year-old mike brown and the ongoing push for justice in his case, but with some protesters there peacefully and others focused on disruption by blocking traffic and sitting in the road, officers nearby took back control. >> we're asking you to continue down canfield. >> reporter: do you think some of those protesters go out there with the intention of trying to provoke police? >> absolutely. many are not from our neighborhood. they're coming in and using this as an opportunity.

>> reporter: do you think the police presence would be better? >> yeah. when they show a lot of force like that, everything like that, it kind of riles them up. >> reporter: today's images, similar to the ones our camera caught last night. some demonstrators seemingly trying to provoke officers to fire. they didn't and the man walked away, but it's one example of the thin line between peaceful protest and chaos. >> when we see violence and we see protests that turns to violence, it frustrates us. it grieves our hearts. not only does it grieve our hearts, but it denigrates the memory of a young man who died on the streets. >> for cbs news, i'm julian johnson, ferguson, missouri. meanwhile, two reporters covering the unrest in ferguson were arrested last night. ryan riley of the "huffington post" and wesley lowery were working inside mcdonald's when

officers in s.w.a.t. gear arrived and told them to leave. >> can i move my -- >> you can move your car if your car is out here. let's go. >> it is. >> both reporters were handcuffed, taken into custody but no charges were filed. riley spoke to cbs news about the incident. >> on my way out, the officer who refused to identify himself by either his name or his badge number pressed his finger up to a pressure point on my neck and -- and forced my hands behind my back as he cuffed me and subsequently purposefully banged my head into the door of the mcdonald's on the way out and then sarcastically apologized. the use of force especially initially was -- seems to me to be antagonistic and unnecessary and, yeah, just really i think escalated the situation more than protected anyone honestly.

>> well, riley says that he and lowrie were released after ferguson's police chief was notified of their arrest. the washington post released a statement calling the arrest unjustified and an assault on press free come. the "huffington post" bureau chief wrote compared to some others who have come into contact with the police department, they came out relatively unscathed but that is in -- in no way excuses the false arrest or the militant aggression towards these journalists. ferguson police have not yet commented on the arrest. this morning a potentially dangerous rescue mission of refugees trapped on a mountain in northern iraq appears unlikely. u.s. troops scouted sinjar mountain yesterday and they found many of the refugees had escaped and that those who remained were in generally good condition. susan mcginnis is in washington. susan, good morning. >> reporter: good morning, anne-marie.

a team of about 20 green berets went into sinjar mountain in blackhawk helicopters and what they found was far fewer refugees than was reported last week. apparently thousands of yazidis were able to leave that mountain each night over the last several nights making the u.s. rescue mission highly unlikely. a possible u.s. military mission to rescue religious refugees now appears to be less likely according to u.s. officials. they say the situation atop iraq's sinjar mountain has become less desperate and many of the refugees have been able to escape with the help of u.s. air strikes. u.s. advisers made the assessment. they were sent to determine if a rescue mission was necessary. tens of thousands of yazidis and christians fled to the mountains over the past few weeks driven from their homes by islamic extremists who demanded they convert to islam or die, but cbs news has learned fewer than 5,000 remain.

defense secretary chuck hagel told reporters yesterday six days of u.s. air strikes have pushed militants away allowing refugees to escape. he said those left behind seem to be doing relatively well thanks to air drops of food and water. secretary hagel said while a u.s. rescue mission now seems unlikely, he won't rule it out completely. he says iraq remains a troubled country and the u.s. effort there is not over. a u.s. military led rescue mission could have involved american ground troops, but the white house insisted their job would have been for humanitarian purposes and not for combat. now brittain, france, and germany are among allies now committing to give supplies to the refugees or equipment to those battles the militants. >> susan mcginnis. thank you, susan. this morning pope francis became the first pope to visit south korea in 25 years. the pope arrived in seoul to begin a five-day visit.
