Rescue crews aided by sniffer dogs dug through crumbled homes Thursday looking for earthquake survivors as Italy again anguished over how to secure its ancient towns and modern cities from the country’s highly seismic terrain.
After a night of uninterrupted, flood-lit search efforts, firefighters and rescue crews worked in teams around the hard-hit area in central Italy, pulling chunks of cement, rock and metal from mounds of rubble where homes once stood, searching for signs of life.
Authorities say at least 247 people were killed and hundreds injured in the quake that struck at 3:36 a.m. Wednesday. At least 470 aftershocks have since rattled the area — one as strong as magnitude 5.1.
