Mexico's Popocatépetl volcano erupted overnight, spewing ash and incandescent material up to 2,000 metres into the air, according to the country's disaster monitoring centre, Cenapred.
Video footage posted by Cenapred director-general Carlos Valdés showed the eruption, with material thrown 400 metres down the volcano's slopes. Residents have been warned to stay outside the 12-kilometre security radius around the crater.
Popocatépetl, an active stratovolcano located 70 kilometres southeast of Mexico City, is one of the country's most monitored volcanoes. Its name means 'smokey mountain' in the indigenous Náhuatl language.
The eruption did not prompt immediate evacuations, but authorities continue to monitor activity closely. Ashfall has been reported in some areas near the volcano.
