The oil company BP has revealed that the cost of tackling the oil spill from a broken well in the Gulf of Mexico has risen dramatically. It now stands at $450m, but it is still rising fast. Jannat Jalil reports.

The oil giant says its attempts to contain the spill are now costing around $33m a day. That's five times more than a figure that was initially calculated. But despite the huge expense it’s incurring, BP has yet to make much progress in stemming the flow of oil. Nearly 13,000 people and more than 500 boats are being deployed to try to skim and direct the oil. Robotic devices have been used, so far, unsuccessfully to try to stop the leak 5000 feet below sea level, and the final bill could be in the billions, as there's still the prospect of future compensation claims and possible fines.

Soldiers in the Thai capital Bangkok have opened fire on anti-government protesters during an operation to seal off an area which the demonstrators have made their base. One protester was killed. The violence came after deadline for the protesters to disperse expired. Rachel Harvey is in Bangkok and told us what happened.

A little while after the deadline when nights had completely fallen, there was a burst of gunfire and an explosion. We know that a renegade army general who has described himself as an adviser to the red-shirt movement to security advisor has been shot and, we believe, is seriously injured. We’ve heard more reports of further gunfire and at least one protester has been shot in the head - shot dead.
