MEXICO CITY (AP) -- The Popocatepetl volcano east of Mexico City has been spewing ash into the sky, forcing cancellation of flights at the nearby Puebla International Airport for a second consecutive day.

The government's airport oversight agency says through its Twitter account Thursday that flights to Monterrey, Houston, Guadalajara, as well as inbound flights from Cancun and Dallas were affected. The agency says the ash is being cleaned up.

Mexico's National Center for Disaster Prevention reports there were a series of frequent, moderate explosions at the volcano overnight.

The national civil protection agency says the volcano is experiencing a period of frequent low-intensity explosions following a series of tremors on Sunday. Similar episodes were observed in May and July 2013, and likely have to do with the growth of a new dome.
