Volcano Eruptions Close Airport

Ash and smoke from erupting Mexican volcano Popocatepetl grounded flights earlier in the week, officials said. Cars in the lot of the Puebla Airport were covered in ash. Flights were canceled on Tuesday but had resumed by Wednesday. In the town of Xalizintla, near the volcano, veterinarians spent much of Wednesday implanting microchips in animals to help track them in case their owners are evacuated.
