Authorities in turkey are blaming isis tonight for a mass Suicide Attack that shattered a wedding party, leaving more than 50 people dead. Adding to the shock, reports that the bomber was a child as well. We get more tonight from nbcs matt bradley. Reporter today in turkey overwhelming grief after a wedding massacre. A suicide bombers savage attack stunned a country where acts of terror have become almost routine. Turkeys president blamed the attack on islamic state. The bomb tore through this narrow street where wedding guests had been dancing. Many would not make it home. People were lying in pools of blood, said this woman who rushed to the scene. I feel powerless. More than 50 were killed and scores injured, many of them children. But perhaps most stunning, officials said the bomber was just a child too, aged 12 to 14. A chilling tactic but not a new one for isis. A lot of these children are orphans or victims of war themselves. So psychologically and emotionally, its much easier for handlers to groom them into being suicide bombers. Reporter turkey is on the front lines of isis. The group is thought to have struck the country many times before, most recently in istanbuls airport, where 45 people were killed. In the heart of istanbuls tourist district in january, and in ankara last year. Its all part of turkeys growing instability.

Casey hunt, nbc news, washington. Near st. Louis, missouri, poor residents of about a dozen small communities are suing their towns, arguing theyre being unfairly punished for minor traffic offenses. The residents say the towns are ganging up against them to raise money, giving them a choice between paying a huge fine or going to jail. We get more from justice correspondent pete williams. Reporter Quentin Thomas, a construction worker from st. Louis, says every time he gets behind the wheel, he worries he will be pulled over by small town police. These traffic stops have cost me a lot of money, also have cost me, you know, career jobs. Reporter in the past four years, he says hes been ordered to pay 1200 in fines and fees for traffic violations and to spend eight days in jail when he couldnt pay. He is part of a newly filed classaction lawsuit accusing 13 area st. Louis towns for arresting and jailing poor and minority residents to squeeze money out of them turning traffic courts into cash cows. No one is arguing there shouldnt be punishments but we cant hold people in jail because they are too poor to pay a debt. Reporter last year alone, the lawsuit says, the touns were so aggressive, they issued one arrest warrant for every adult. And the suit contends the towns are in it together. They say failing to appear in a charge in one generates a warrant for others to use as a chance to make an arrest and collect more money the Justice Department found similar Court Practices contributed to the resentment that led to rioting in ferguson, missouri after the shooting of michael brown. For their part several of the towns say they take in less through their courts than state law allows, and they insist that every case begins when someone actually breaks the law. Those laws are there for a reason. Its got nothing to do with filling coffers. Its got everything to do with trying to make the streets safe and implementing the law in as fair and partial manner as possible. Reporter though Quentin Thomas says jail cost him his car and two jobs, he is back at work, but still worried when he is on the road. Pete williams, nbc news, washington.
