BUENOS AIRES - A thick cloud of ash from a Chilean volcano brought airports to a halt in Argentina and neighboring Uruguay on Thursday, forcing airlines to cancel dozens of flights, airport officials said.
A volcano dormant for decades erupted in south-central Chile during the weekend, belching an ash cloud that blew over the Andes and has been disrupting air traffic in South America for days.
"Due to the movement over the Buenos Aires metropolitan area of a new ash cloud from the Puyehue volcano, flights (to and from) the Ezeiza and Aeroparque airports have been canceled," the transport authority said in a statement.
Buenos Aires is a key air hub for South America, with dozens of daily flights to other countries in the region, as well as Europe and the United States.
