Media reports in the United States say investigators have identified a suspect in the Boston marathon bombings from video footage. The reports said the authorities had an image of the suspect carrying a bag at one of the bomb sites. Officials have denied media reports that an arrest has been made. An official announcement from the FBI is expected in the coming hours. Three people were killed and more than 170 injured in the blasts. Host Aaron Schachter gets an update from The World's Arun Rath.
