STOCKHOLM - Iceland's aviation authority said on Monday it hoped to reopen the island's main airport later today or tonight after it was closed due to an eruption at the country's most active volcano at the weekend.

"It looks better today and we are hoping to reopen Keflavik airport later today or tonight. We are not quite sure at what hour, but at least we are looking at it being possible," aviation authority spokeswoman Hjordis Gudmundsdottir said.

Keflavik is Iceland's main airport, located near the capital Reykjavik.

Gudmundsdottir said there were indications that the ash cloud could be clearing above the North Atlantic island, though it was too soon to know for sure and that a more detailed assessment would be made later on Monday.
