California firefighters tackling six major wildfires

More than 3,000 firefighters are battling six major wildfires in California, the state fire agency says.

One of the fiercest blazes has shut the famous Pacific Coast Highway for the second time in as many days, with a 30-mile (50-km) stretch off-limits.

The so-called Springs fire has reached the coast north-west of Los Angeles, threatening thousands of homes.

Fire crews have tackled more than 680 wildfires so far this year, some 200 more than average for the period.

The Springs fire has tripled in size since Friday morning, burning 43 sq miles (69 sq km), a day after it broke out near Camarillo.

The blaze has damaged more than a dozen homes, with another 4,000 at risk. No injuries have been reported.
