Rescuers in Ecuador pulled three people out alive after being trapped for more than 32 hours in the rubble of a shopping center that was flattened by this weekend's powerful earthquake.
Televised images of the dramatic pre-dawn rescue Monday in this port city gave Ecuadoreans hope that scores of people still unaccounted for may yet be found even as the death toll from Saturday's 7.8-magnitude quake climbed to 413.
Ecuadorian officials gave the latest update on the number killed Monday evening.

At least one American was among those killed. State Department spokesman John Kirby hasn't identified the dead American, but says U.S. officials have been in touch with the victim's family.
To reach the survivors amid the debris in Manta, firefighters cut a nearly 2 ½-foot (70-centimeter) hole in the concrete, through which they pulled a woman. A group of firefighters applauded as she emerged head first from the debris, disoriented, caked in dust and complaining of pain but otherwise in good health.
Later, at the same site, they managed to rescue another woman and a young man. All three were rushed in ambulances to a nearby hospital. Authorities said another woman remained trapped and was being given water and other supplies while rescuers attempt to remove a heavy concrete slab pinning down her legs.
Christian Rivera, the head of emergency services for the capital, Quito, said that depending on the circumstances a person without serious injuries can survive up to a week under the rubble.
"After that, there's a quick decline ... and the rescuers' work becomes very difficult," he said in an interview.
Still, there are good reasons to believe more people will be found alive in the coming hours as some 450 rescue workers from Spain, Chile, Mexico and elsewhere reached the most-affected areas along the Pacific coast.
President Rafael Correa, upon arriving in Manta late Sunday, said the priority remains finding survivors.
"Our grief is very large, the tragedy is very large, but we'll find the way to move forward," Correa said, adding that the quake was the worst to hit Ecuador since one in 1949 that took over 5,000 lives. "If our pain is immense, still larger is the spirt of our people."
Manta, a thriving port city, was among the hardest-hit areas. Among the many building that were flattened was a control tower at the airport that was home to U.S. anti-narcotics missions in South America until Correa, a critic of the U.S.-led war on drugs in Latin America, kicked the Americans out.
As rescuers scrambled through the ruins near the epicenter, in some cases digging with their hands to look for survivors, humanitarian aid began trickling in. More than 3,000 packages of food and nearly 8,000 sleeping kits were delivered Sunday.
The Saturday night quake knocked out power in many areas along the coast and some who fled to higher ground fearing a tsunami had no home to return to or feared structures still standing might collapse. The country's Geophysics Institute said it recorded 230 aftershocks as of Sunday night.
Spain's Red Cross said as many as 5,000 people may need temporary housing after the quake destroyed homes, and 100,000 may need some sort of aid.
Aggravating matters were reports of looting, including in Manta, where 180 prisoners from a nearby prison escaped amid the tumult. Authorities said some 20 inmates were recaptured and others returned voluntarily.
