in ferguson. right now it appears mostly calm on the streets here. earlier today, though, it was a day of peaceful protests again interrupted by violence. police officers in riot gear ordered people off the streets of ferguson overnight as a second night of a mandatory midnight curfew went into effect. just hours before, authorities fired tear gas into a crowd as protesters hurled rocks in their direction. >> molotov cocktails were thrown. there were shootings, looting, vandalism and other acts of violence. we had to act to protect lives and property. >> reporter: resident keith smith said he was in the middle of the chaos. >> my eyes were burning. i couldn't see. i couldn't really breathe. >> reporter: many people here in ferguson remain angry at the officer responsible for using deadly force when they believe brown was surrendering. ferguson police maintain brown attacked the officer in his car and tried to take his weapon.

as a sign of growing federal involvement, the justice department says it will conduct its own autopsy on brown's body as soon as possible. because of the unrest, all schools in the ferguson school district will be closed today. now, on sunday at a memorial service, captain ron johnson, he is the head of the highway patrol here now in charge of security here, he spoke and he apologized to the brown family. then at a press conference just a short while ago, he spoke again talking about a day that started with unity and prayers and then took a different turn at night. lauren? >> susan mcginnis in ferguson, missouri. susan, thanks. and president obama is back in washington where he'll be briefed on the tensions in ferguson as well as other issues. the president returned to washington last night, a break from his vacation in martha's vineyard. he'll meet with vice president biden and others before resuming his vacation again tomorrow. overseas, the u.s. has upped the ante against islamic

half mile away, and they're a moving target. >> because they're moving like guerrilla moving from there to there. >> get down! >> reporter: we soon learned how close that was as mortar fire exploded around us. the position is on the outski outskirts, the closest the extremist group has been to the kurdish capital of erbil. a week ago this town was empty of its residents and instead full of isis militants. that was before kurdish forces succeeded in pushing them out. now these former refugees are back home. shabab escaped with his wife and seven children when isis overran the town. what is it like to be back home? "i'm really happy to be home," he told us, "but there's no water. part of the town has no electricity." and although isis may have been pushed back for now, everyone here knows they're not far away.

to get an austin prosecutor, rosemary lehmberg, a democrat, to step down. he threatened to withhold state funding for her office. perry said he took the action after her arrest on drunk driving charges. >> this is not the way that we settle differences, political differences, in this country. you don't do it with indictments. we settle our political differences at the ballot box. >> perry can continue to serve as governor while under indictment. he is the first sitting texas governor to be indicted since 1917. coming up the "morning news," deadly train collision. a head-on crash forces hundreds of evacuations in arkansas. and we'll go back live to ferguson, missouri, following another night of violent protests. this is the "cbs morning news." with psoriatic arthritis, i had intense joint pain that got worse and worse. then my rheumatologist prescribed enbrel.
