More sad news out of Italy: Two days after a deadly earthquake, a 5.5 magnitude aftershock has ripped through already damaged towns, killing another person. Rescuers, searching by lamplight for a second night after the quake that has killed at least 235, are desperately searching for more survivors, after a 20-year-old woman was found in the wreckage of a four-story building 42 hours after the quake. “A rescue like this is worth six months’ work,” said a fireman at the scene. Prime Minister Silvio Berlusconi, who so far has refused aid from Barack Obama and other world leaders, said about 7,000 rescuers would continue searching for another 48 hours after the country’s worst earthquake in 30 years. More than 150 people have been found alive under rubble so far, while more than 1,000 have been injured and about 20,000 left homeless.
