A huge wildfire in northern California has spread further into Yosemite National Park, although about 30% of the blaze is now contained.
Emergency crews have been attacking the eastern flank of the fire, trying to prevent the flames spreading deeper into the heart of the park, towards Yosemite Valley. But their work is hampered by the terrain.
Officials say it could take several weeks to fully contain the fire, which started west of the park on 17 August.
The Rim Fire now covers more than 192,000 acres. On Wednesday, it forced the closure of another road into Yosemite, before the Labor Day weekend.
