Energy giant BP has installed a new cap that it hopes will enclose a ruptured deep-sea oil well in the Gulf of Mexico.

The company needs to gradually shut the valves to ensure the well can handle added pressure.

If the attempt is successful, it would mark the first time in nearly three months that oil stopped flowing into the waterway. But BP has acknowledged that this fix is only a temporary solution.
