Reykjavik - In the second case of its kind in two weeks, a polar bear was sighted in northern Iceland after apparently making a journey of several hundred kilometres atop an ice floe from Greenland, the broadcaster RUV reported Tuesday.

A 12-year-old girl on a farm near the town of Saudarkrokur, on the Skaga fjord, spotted the bear on Monday and alerted the authorities.

Two weeks earlier, another polar bear was spotted in Iceland, which lies just below the Arctic Circle in the North Atlantic - the first such spotting in 20 years.

In the earlier case, authorities permitted police marksmen to kill the polar bear, sparking protests from environmentalists and animal rights' groups.

After the protests, authorities are now making plans to capture the second bear and have it shipped in a cage back to Greenland. (dpa)
