Survivors were mourning while battling shortages of food and shelter, but searches of the scores of flattened apartment buildings have carried on and saved lives.A three-year-old boy was rescued alive from the rubble in Caracas on Tuesday, a Jordanian rescue team said, a full six days after Venezuela's most powerful quake in over a century."We're late, we're very late... but our aim is to keep saving lives, to be able to save those citizens who are trapped under the rubble, who still need us," said Luis Arteaga Benatuil, member of Spanish search and rescue group, after landing arriving Wednesday in Venezuela.The rescues have come long after the 72-hour period considered critical for survival and as the UN refugee agency said "food shortages are widespread in hard-hit port city of La Guaira."The situation is quite critical," said Lia Poggio, head of mission in Venezuela for the International Organization for Migration (IOM).The 7.2 and 7.5 magnitude shocks -- one of the worst earthquake disasters in Latin American history -- collapsed whole residential complexes on June 24 and prompted frantic search-and-rescue operations for survivors trapped in the ruins.Venezuela's National Assembly President Jorge Rodriguez said Tuesday that deaths had risen to 1,943, with more than 10,500 injured after one of Latin America's worst earthquake disasters. He added that nearly 6,500 people had been rescued from the rubble in La Guaira, but that number was likely closer to 20,000 including those who escaped or were helped out by family.Many Venezuelans have not hidden their anger at the government's slow response to the disaster in a country already struggling with decades of economic crisis that has weakened infrastructure and health services."They give out supplies here, but sometimes people nearly kill each other for food... It's like a cockfight," Daniela Armas, 18, a vendor in La Guaira, said after waiting to get food an emergency shelter.
