Two people have been killed in an earthquake in Ecuador, with eight others wounded and rescue workers still seeking to free those trapped.
The 5.1-magnitude tremor near capital Quito triggered a landslide at a quarry that killed two workers there, the national risk control agency said, adding that firemen were searching for three others.
"Obviously the landslide was caused by the tremor, but there was already weakness there due to illegal mining … or quarries being exploited improperly," President Rafael Correa told reporters in the port city of Guayaquil.
Separately, the mayor of Quito reported that only one person died in the landslide and that a four-year-old boy was killed in another part of the city when sacks of rice fell on top of him.
Social media showed images of dust clouds that had formed after the tremor as a result of shifting earth.
The city's main airport returned to normal operations after earlier halting flights as a precautionary measure.
The tremor snarled traffic in the city of 1.6 million and led startled office workers to stream out of buildings.
"We could really feel it. The first thing I did was leave (the building) with my colleagues," said Teresa Salazar, 45, who works at an imports business in northern Quito. "There was nothing major to report, but we were all very nervous."
The US Geological Survey said the moderate quake was only 4.8 miles (7.7 km) deep, with its epicentre located 14 miles (22.5km) north-east of Quito.
