BUENOS AIRES, June 7 (Xinhua) -- Argentina's main airports in Buenos Aires reopened Tuesday after ashes spewed by a volcano in Chile grounded all flights for two days.
Ezeiza International Airport has been reopened and domestic and regional flights at the Metropolitan Airport have been resumed, though some smaller airports remain closed, transportation authorities said.
Safety of air traffic in the reopened terminals can be guaranteed, said the authorities.
Chile's Puyehue volcano on Saturday erupted for the first time in half a century.
Earlier, more than 100 flights have been canceled in Argentina due to a towering plume of ash blown into the country's air space from the volcano. In Chile, flight cancellations were also imposed in Santiago airport.
Besides Argentina, the cloud of volcanic ashes also reached the southern region of Brazil.
So far, the cloud is restricted to the Brazil-Uruguay border region and would not affect the air traffic in the nearby city, according to sources of the Brazilian Air Force.
However, flights between Brazilian cities and four other South American countries - Argentina, Uruguay, Chile and Paraguay - had to be canceled because of danger caused by the smoke in those areas, according to local airliners.
On Tuesday alone, Brazil's TAM airline company canceled a total of 32 flights, and Gol airline canceled 19.
