The Associated Press is reporting that stiff winds blew ash from a Chilean volcano Tuesday in a widening arc across Argentina to the capital, grounding most air travel to and from the country.
Since airborne ash can severely damage jet engines, Aerolineas Argentinas and Austral, the country's state-owned international and domestic airlines, canceled all flights within Argentina as well as to and from other countries until further notice.
According to the report, at least six international carriers also suspended flights through Wednesday between Buenos Aires and cities in the U.S., Europe and South America. Other carriers were expected to follow. Flights from Chile over Argentine territory also were suspended.
