Bahrain's Crown Prince and F1 boss Bernie Ecclestone have defended the decision to go ahead with this Sunday's Grand Prix in the Gulf state.

Security around the capital has been stepped up at the start of what protesters are calling "three days of rage", with fresh clashes between the demonstrators and security forces.
