Officials say more than 70 people have been killed in an earthquake in central Italy and that 1,500 people have been injured. Premier Silvio Berlusconi and civil protection chief Guido Bertolaso spoke to reporters after reaching the central Italian city of L'Aquila. The city was hit by a powerful earthquake as residents slept early Monday. Berlusconi warned that more quakes were possible and said no one would be allowed to remain in damaged homes. He said many buildings in the city's historic center were at risk of collapse. Bertolaso told reporters that "the victims are even more than 70." The quake struck about 110 kilometers northeast of Rome at 3:32 a.m. local time, officials said.
