Desperate Venezuelans and foreign rescuers raced to find survivors trapped under rubble on Friday after twin earthquakes flattened parts of Caracas and surrounding areas, as frustration mounted over a lack of heavy equipment and the death toll neared 1,000. Foreign rescue teams and aid began arriving nearly two days after magnitude 7.2 and 7.5 tremors struck about 160 km (100 miles) west of Caracas.
