At least six people have been confirmed dead following an earthquake in Italy.
The quake, which measured 6.2 on the Richer scale, struck overnight near the city of Perugia but was felt some 170km away in Rome.
It caused buildings to collapse leaving some people trapped under rubble, officials said.
The Mayor of the town of Accumoli said four of those trapped were two adults and two children who "are not showing any signs of life".
The mayor of the small nearby town of Amatrice Sergio Pirozzi said: "Half the town is gone.
"There are people under the rubble. There's been a landslide and a bridge might collapse."
Resident Matteo Berlenga said the quake was "the worst I've felt in my life".
Lina Mercantini of Ceselli, Umbria told Reuters: "It was so strong. It seemed the bed was walking across the room by itself with us on it."
Olga Urbani, in the nearby town of Scheggino, said: "Dear God it was awful. The walls creaked and all the books fell off the shelves."
Prime Minister Matteo Renzi's spokesman said on Twitter that the government was in touch with the country's civil protection agency.
The last major earthquake to hit Italy struck the central city of L'Aquila in 2009 killing more than 300 people.
