Areas of Mosul still under siege, but signs of life return

Iraqi forces, backed by U.S. support, have retaken one side of the city of Mosul. Now a military offensive to recapture the rest of the city -- where hundreds of thousands of civilians are still trapped -- is expected to start at any time. And yet, a short distance away, signs of life are returning to the city. Special correspondent Jane Ferguson and videographer Alessandro Pavone report.
