Iceland Volcano Eruption

I found this link on YouTube about the volcano eruption in Iceland. I also typed the script in the video for your understanding.

Volcanic ash from Iceland that has blurred across northern Europe has severely disrupted air traffic across the U.K., Ireland and Scandinavia.

The next two hours all flights in British airspace will be suspended, grounding hundreds of planes including those in the world’s busiest international airport at Heathrow, London.

The ash is dangerous to aircraft because the tiny particles can damage engines, causing them to shut down.
