MEXICO CITY (AP) -- An airport serving Mexico's fourth-largest city has suspended operations due to volcanic ash from the Popocatepetl volcano.
The international airport in Puebla was temporarily closed as a precautionary measure.
The airport is east of Mexico City and about 20 miles (30 kilometers) from the 17,886-foot (5,450-meter) volcano.
Airport spokesman Herbert Lopez Palma said Friday that the ash could pose a risk in takeoff and landing.
Flights to several Mexican cities as well as to Dallas and Houston, Texas, use the airport.
Authorities said this week that a lava dome is growing inside the crater and could cause further eruptions.
