Double earthquake kills hundreds in Venezuela; rescue teams race against time

Two major earthquakes struck Venezuela on June 26, killing at least 920 people and leaving hundreds missing. The damage concentrated in Caracas and La Guaira, a coastal area hemmed in by mountains that makes rescue work difficult. Venezuela's weak emergency services and poorly built structures worsen the crisis. Foreign rescue teams have arrived, but the critical 72-hour window for finding survivors is already passing.
