NY Malls on Alert After Al Shabab Threats

Authorities say there is no credible threat, but stores in New York and around the country are on heightened alert – following a new terror video calling for attacks on shopping malls in western countries. The video is purportedly from al Shabab, the Al-Qaeda linked terror group in Somalia responsible for that horrific mall attack in Nairobi, Kenya back in 2013. Greg Cergol reports.
