Dozens of migrating reindeer have been killed by speeding freight trains in three days in northern Norway.

Reindeer herder Torstein Appfjell said he was “dizzy with anger” after losing 106 animals since 23 November in Helgeland county.

Mr Appfjell, who represents four families who look after around 2,000 reindeer in the area, lost 65 animals in the worst incident.

The reindeer were killed while crossing a train track which runs through a migration route they follow towards the coast as winter approaches.

Mr Appfjell told AP the high number of reindeer deaths was “unprecedented”, adding that 250 of the animals had been killed in train accidents in the worst previous 12-month period.
