US blaze grows to seventh biggest ever in California
SAN FRANCISCO, California, Aug 27, 201 (AFP) - The wildfire threatening Yosemite National Park grew on Tuesday to become the seventh biggest ever in California, as firefighters battled to keep ash from contaminating San Francisco's main water supply.
The so-called Rim Fire now covers 72,633ha, taking it into California's top 10 biggest ever blazes from 13th on Monday.
By Tuesday it was 20 per cent contained, up from 15 per cent the previous day.
A main road into Yosemite, one of America's top tourist destinations, remains closed as more than 3,700 firefighters battle the flames.
