Iceland volcano 'ready to erupt'

One of Iceland's most feared volcanoes looks ready to erupt, experts say, raising fears of a new ash cloud halting flights over Europe.

The Hekla volcano is close to the ash-spewing Eyjafjallajkull, which last year caused the biggest closure of airspace since World War II.

Hekla has erupted about 20 times over the past millennium, most recently on February 26, 2000.
