Oklahoma tornado: Mayor pushes for shelter law

The mayor of the tornado-devastated town of Moore in Oklahoma has vowed to push for a new law on shelters, after a huge twister there killed at least 24.

Glenn Lewis said he would propose an ordinance requiring a reinforced shelter to be built in every new home.

Volunteers are now engaged in a recovery mission - delivering supplies and helping people find accommodation.

Mark Mardell reports from Moore.
