Ash from the erupting Cumbre Vieja volcano has forced authorities in Spain's La Palma to close the airport on the island, Spanish air traffic operator, Aena said.

"The airport is not in operation at the moment," an AENA spokeswoman told AFP, saying "some cleaning work needs to be done" on the runways before it would reopen.

"The closure may not last very long," she added.

Other airports in the Canary archipelago remained open, authorities said.

The volcano started blasting out jets of red-hot lava on 19 September, laying waste to hundreds of buildings and farms, and forcing the evacuation of thousands.

This is the second time that thick ash from the erupting volcano has forced the island's airport to close.

Yesterday evening, local airline Binter had said it was cancelling all flights in and out of La Palma, one of Spain's Canary Islands archipelago in the Atlantic, just off the northwestern coast of Africa.

"This suspension will last until conditions improve and we can fly safely," Binter tweeted, with rival airline Canaryfly also suspending flights.

The airport was briefly shut on 25 September after a thick cloud of black ash forced airlines to cancel flights.

Although it was reopened a day later, flights did not resume until 29 September.
