Mexican volcano explosion sends ash over city
Mexico's Popocatepetl volcano has seen a dramatic overnight explosion that sent ash blowing over the major city of Puebla directly to the east, forcing closure of its airport.
Officials there are urging people to wear masks to avoid inhaling the fine grit that has covered houses and cars.
The eruption began at around 2.30am (7.30am GMT) today, hurling glowing rock as far as a mile from the crater, Mexico's national disaster prevention agency reported. Ash rose nearly two miles above the crater.
About 25 million people live within 62 miles of the crater of the 17,797ft stratovolcano. It has been periodically erupting since 1994.
