Scuffles at Madrid's main airport as a strike turns nasty. Iberia airline workers stormed the building. It's day one of a five day strike over pay cuts and the loss of 3,800 jobs. The action follows Iberia's merger with British Airways in 2011. The combined International Airlines Group has been trying to revamp its Spanish operation ever since. This is the latest in a string of disputes and the biggest yet - it involves pilots, cabin crew and baggage handlers.
