Local and international rescue teams raced against the clock to pull survivors from the rubble in Venezuela four days after two powerful earthquakes shook the northern state of La Guaira. The government reported 1,450 dead from the quakes Sunday afternoon as it faced growing criticism from Venezuelans that its response was inadequate and overshadowed by civilian-led search-and-rescue efforts. Thousands have been reported missing. Even as the likelihood of finding people alive diminished with each passing hour, rescuers continued to free survivors from mountains of debris, offering anguished families reason to keep hopes alive.
