Quake-damaged roads threaten access to Italian town

Strong aftershocks have damaged two key access roads into quake-struck Amatrice, threatening to isolate the tiny Italian hilltop town as hopes fade that firefighters will find any more survivors from the earthquake that killed at least 267 people.

Some crumbled buildings in Amatrice cracked even further after the biggest aftershock of Friday morning struck at 6.28am local time. The US Geological Service said it had a magnitude of 4.7, while the Italian geophysics institute measured it at 4.8.
