Many of the dead were in Accumoli, close to the epicentre, and a short distance away in Amatrice, where three-quarters of houses were destroyed. While the full extent of casualties is still emerging, Italian news agency Ansa is reporting that it believes at least 73 people have died. Many people are still believed buried under the rubble, and the death toll is expected to rise. For updates at the BBC, click here.
