Tourists more than 100 miles away from the epicentre of an earthquake that has hit central Italy were woken by the tremors.
The magnitude 6.2 quake had its epicentre in Norcia in Umbria, about 105 miles north east of Rome.
The hardest-hit towns were reported as Amatrice, Accumoli and Norcia and there are thought to be multiple fatalities.
Sarah Conrad, who works for YouTube in London and is visiting the Italian capital, said she was woken up in the early hours and also felt aftershocks.
She tweeted: "Pretty sure I was just woken up by an #earthquake in #rome.
"I thought someone snuck into my hotel room & was jumping on the bed. Both scary!"
Paul O' Halloran, whose Twitter profile said he was in Rome said: "Just got woke up by an earthquake! Bed and window shutters moving!"
Toby Shaw, from Hampshire, tweeted: "I'm really hoping that I've just experienced an #earthquake in #Rome, otherwise I'm not sure I want to know what it was that shook the room."
Ryan Sloan, a lawyer based in Glasgow, described the moment the earthquake woke him in Rome as the "most terrifying moment" of his life.
He said: "Woke up as felt like someone violently rocking bed."
