Four flights bound for Europe out of Vancouver were cancelled Thursday, after clouds of ash caused by volcanic activity in Iceland closed airports across the continent.

Two flights bound for London Heathrow airport as well planes headed for Frankfurt and Amsterdam were grounded, and one flight to London Gatwick airport has been delayed.

Two inbound flights were cancelled from London and Amsterdam.

Air Canada says it has cancelled all flights to and from London's Heathrow airport, Charles de Gaulle airport in Paris and the Frankfurt airport until further notice.

Airports across Europe were forced to close after an erupting volcano in Iceland spewed a treacherous ash cloud, closing all air space over Britain, Ireland and Nordic countries.

Experts say the ash, comprised of bits of sand and glass the consistency of talcum powder, compromises visibility for pilots and aircraft engines.

The Vancouver International Airport is recommending that passengers with flights scheduled for European destinations check the YVR website or with their airlines to stay updated on flight status.
