Ecuador declares state of emergency over volcano
Ecuador President Rafael Correa has declared a state of emergency over increasing activity at the Cotopaxi volcano near the capital, Quito.
The declaration gives authorities more flexibility in using government funds to address the situation.
Officials evacuated several hundred people from nearby villages after the volcano began to erupt on Friday.
Cotopaxi is among the world's most dangerous volcanoes and is prone to fast-moving rock and mud flows.
Small eruptions have already shot ash more than 5km (three miles) into the sky, spreading fine grey powder over an area as far as the capital 50km (30 miles) to the north.
Authorities have restricted access to the park that surrounds the volcano and barred mountaineers from climbing the snow-capped peak.
Cotopaxi last had a major eruption in 1877.
