Rescue continues as anguish mounts

70 percent of country's buildings are not built to anti-seismic standards

Rescue crews raced against time on Thursday looking for survivors from the earthquake that leveled three towns in central Italy, but the death toll rose to nearly 250 and Italy once again anguished over trying to secure its medieval communities built on seismic lands.

Dawn broke over the rolling hills of central Lazio and Le Marche regions after a night of uninterrupted search efforts. Aided by sniffer dogs and audio equipment, firefighters and rescue crews using their bare hands pulled chunks of cement, rock and metal apart from mounds of rubble where homes once stood searching for signs of life.
