Volcano ash halts Argentine planes
Ash from a Chilean volcano has stretched across Argentina to Buenos Aires, grounding most air travel to and from the country.
Aerolineas Argentinas and Austral, the country's two state-owned airlines, have cancelled all flights until further notice.
International air carriers Delta, American, United, Gol, and TAM air lines have cancelled flights to and from the airports in Buenos Aires as a precaution, and other carriers are expected to follow.
Airborne ash can severely damage jet engines.
Aviation regulators are meeting to decide whether to shut down the capital's airports altogether as a precaution from the volcano ash that began blowing on Saturday.
