BP finally seals leaking Gulf of Mexico oil well

The ruptured well that has spewed millions of barrels of oil into the Gulf of Mexico has finally been sealed, US officials say.

The worst offshore oil spill in US history began after the Deepwater Horizon rig blew up on 20 April, killing 11 workers and later sinking.
