Arctic ice island breaks in half

The giant Ayles Ice Island drifting off Canada's northern shores has broken in two - far earlier than expected.

In a season of record summer melting in the region, the two chunks have moved rapidly through the water - one of them covering 98km (61 miles) in a week.

Their progress has been tracked amid fears they could edge west towards oil and gas installations off Alaska.

The original Manhattan-sized berg (16km by five km; 10 miles by three miles) broke off the Ayles Ice Shelf in 2005.
