(AP) -- The cloud of ash spewing from Chile's erupting volcano has grounded more flights in countries from Uruguay to Australia and is threatening to delay next month's start of the Copa America football tournament in Argentina.
Argentine Football Association president Julio Grondona says the July 1 start of the Copa America could be pushed back due to cancelations of flights caused by the volcano.
Grondona tells the Argentine broadcaster Radio 10 that "from no point of view are all the countries prepared to come to Buenos Aires" in time.
The main international airports in Argentina and Uruguay were closed on Tuesday, and across the Pacific more Australian flights were canceled because of ash from Chile's Cordon Caulle volcano.
