Residents of towns in central Italy devastated by an earthquake were rattled by a series of aftershocks overnight, as the nation began a day of mourning.

Strong aftershocks have rattled central Italy and shut down a key route into the hard-hit town of Amatrice as hopes faded that firefighters would find any more survivors from the earthquake that killed at least 267 people.
