Around 4,000 fire fighters are still struggling to contain a huge wildfire that has been burning for the past 11 days near California's Yosemite National Park.

The blaze is now spreading inside the park itself and main roads into Yosemite are being closed off.

The so-called Rim Fire is one of the biggest ever seen in California and now covers close to 300 square miles.
