Island Volcano Ash Spread | U.K Airport Closure

Many airports were shut and flights were grounded across the United Kingdom on Thursday because of ash from a volcanic eruption in Iceland, airport authorities said.

Ash from Iceland has prompted aviation officials to restrict flights over parts of Norway and the United Kingdom.

The ash also caused delays in some flights leaving the United States, the Federal Aviation Administration said.

"There are some ground holds in place for flights that would be going through Icelandic air space due to volcanic ash," FAA spokeswoman Laura Brown said Wednesday night.
