At least 413 people are now known to have died in the earthquake that struck Ecuador, the country's government says, according to the BBC.

The 7.8-magnitude quake struck Ecuador's Pacific coast on Saturday, and the search for survivors continues.

The cost of rebuilding is likely to be in the billions of dollars, President Rafael Correa said during a visit to the worst-affected region.

He said it was the biggest tragedy to hit Ecuador in the past seven decades. Some 2,500 people were injured.

"I fear that figure will go up because we keep on removing rubble," a shaken Mr Correa said in a televised address. "There are signs of life in the rubble, and that is being prioritised."

The president warned that the quake will cost Ecuador billions of dollars. It comes at a time when the oil-producing country is already reeling from the slump in global crude prices.
