"Giant Iceberg Splits From Antarctic"

"One of the biggest icebergs ever recorded has just broken away from Antarctica.

The giant block is estimated to cover an area of roughly 6,000 sq km; that's about a quarter the size of Wales.

An US satellite observed the berg on Wednesday while passing over a region known as the Larsen C Ice Shelf. "
