Santiago: The ash cloud from a Chilean volcano that has been erupting for nearly two weeks has encircled the globe and has come home again.

The returning cloud - which has disrupted flights in Argentina, Brazil, Uruguay, Australia and New Zealand on its around-the-world trip - forced Chilean officials to cancel domestic flights for the first time since the Cordon Caulle volcano began erupting on June 4.

LAN airlines suspended flights to the cities of Puerto Montt, Coyhaique and Punta Arenas in the far south of the South American country. While ash from Cordon Caulle has wreaked havoc with air travel abroad, it had left Chile's internal flights largely untouched until Friday.

"The tip of the cloud that has travelled around the world is more or less in front of Coyhaique," said Civil Aviation Office chief Pablo Ortega. Coyhaique is 800 kilometers (500 miles) south of the volcano.

Chilean authorities evacuated 3,500 people living near the volcano after it began erupting but since then, some have managed to return.
