5 Videos Showing Massive Damage From Northern Italy's Deadly Quake

At least six people were killed and dozens injured in northeast Italy early Sunday after what was said to be the strongest earthquake to shake the region in hundreds of years.

The magnitude-6.0 temblor struck at 4:04 a.m., with its epicenter about 22 miles north of Bologna.

An Italian official told the Associated Press it was the worst quake the area had seen since the 1300s, leaving cracked bell towers, chunks of church facades lying in the streets and caved-in roofs.
