An ice bridge linking a shelf of ice the size of Jamaica to an island in Antarctica has snapped.
Scientists suggest the collapse could mean that the Wilkins Ice Shelf is on the brink of breaking away, and that it provides evidence of global warming.
The shelf has been retreating since the 1990s, but scientists say this is the first time it has lost one of the connections that keeps it in place.
It broke off at the thinnest point of the 40-km (25-mile) strip of ice.
A European Space Agency satellite picture shows newly created icebergs floating in the sea on the western side of the Antarctic peninsula, which juts up from the continent towards South America’s southern tip.
