Thousands Feared Dead in Haiti

Haitian President René Préval said the toll of Tuesday's earthquake was "unimaginable" and estimated that thousands are dead in what President Obama called "a truly heart-rending situation." The quake, centered about 10 miles west of the capital city, Port-au-Prince, had a preliminary magnitude of 7.0 and was followed by at least eight powerful aftershocks—the strongest earthquake to hit the island, experts say, since 1770. The headquarters of the U.N. mission to the island is among the collapsed buildings, and more than 100 of its employees are missing. Obama promised to address with a "swift and aggressive" relief effort.
