The Cumbre Vieja volcano on the Canary Island of La Palma, in El Paso, Spain, spews lava and emits smoke on Saturday, around a week after it erupted.

Reuters drone footage showed a rapid river of red hot lava flowing down the slopes of the crater, passing close to homes, and swathes of land and buildings engulfed by a black mass of slower-moving, older lava.

Spain’s airport operator Aena said the airport had reopened after teams cleared ash off the runway. But Binter, the Canary Island airline, said it would keep flights cancelled on Sunday because of the conditions.

“The ash cloud originating from the volcanic eruption makes it necessary to maintain the temporary stoppage of flights to La Palma... The flights scheduled for today have been cancelled,” it said in a statement. “The stoppage will continue until conditions improve.”

Spanish media reported all flights would remain cancelled on Sunday.

The volcano, which began erupting last Sunday, entered a new explosive phase on Friday, experts said.

The eruption has destroyed hundreds of houses and forced the evacuation of nearly 6,000 people since it began on September 19.
