The massive oil spill in the Gulf of Mexico has reached landfall, threatening an environmental catastrophe in the region.
The spill began a week ago when an oil rig exploded and sank.
Officials set up thousands of meters of booms to protect coastal areas. But rough seas sent oily water over them into the Mississippi river on Thursday evening local time, 24 hours earlier than expected.
Some news agencies are reporting that “faint” traces of the oil are lapping the Louisiana shoreline.
Experts say the slick threatens hundreds of species of fish, birds and other wildlife in the region.
