BREAKING: Oil Rig That Had Explosion Sinks

The Coast Guard is saying an oil platform that suffered a massive explosion two days ago has sunk in the Gulf of Mexico.

Coast Guard Petty Officer Katherine McNamara said Thursday that the Deepwater Horizon had gone under. The Coast Guard is still searching for 11 workers who went missing after the blast Tuesday.

The rig had been burning since the explosion. Supply vessels had been shooting water at it to try to control the flames and prevent the platform from sinking.

The rig is about twice the size of a football field. It is owned by Transocean, which is under contract to oil giant BP.

The rig was doing exploratory drilling about 50 miles off the coast of Louisiana.
