Strikes turn US ports into ghost towns

Clerical workers have been on strike at the US ports of Los Angeles and Long Beach for more than a week.
The strikes have brought operations to a screeching halt and shut down the major passage for goods from Asia.
Both sides are willing to sit down with a federal mediator, but the strike is still costing the US economy up to $1bn a day.
The BBC's David Willis reports from the port of Long Beach.
