Swedish archaeologists have discovered a rare hoard of Viking-age silver Arab coins near Stockholm's Arlanda airport.

About 470 coins were found on 1 April at an early Iron Age burial site. They date from the 7th to 9th Century, when Viking traders travelled widely.

There has been no similar find in that part of Sweden since the 1880s.
