A strong earthquake hit the impoverished Caribbean country of Haiti on Tuesday afternoon, collapsing a hospital and damaging other buildings in and around the capital, Port-au-Prince. The earthquake had a magnitude of 7.0 and was centered about 22 kilometers west of the capital, the U.S. Geological Survey (USGS) said. It noted that there was a 5.9-magnitude aftershock. The Associated Press reported the collapsed hospital in Petionville, and a U.S. government official reported seeing houses that had fallen into a ravine.
