Chile forest blaze kills six firefighters in Araucania

---

At least six firefighters have died battling a blaze in a mountain forest in southern Chile, the authorities say.
Two others were badly burned in the fire in the Araucania region.
Over the past week multiple forest fires have ravaged large areas of central and southern Chile.
President Sebastian Pinera says some appear to have been started deliberately, and has invoked an anti-terrorist law to pursue anyone responsible.
The six volunteer firefighters who died were part of a team trying to extinguish a blaze near Carahue in the Araucania region, about 700km (434 miles) south of the capital Santiago.
They were trapped by flames when the wind suddenly changed direction, officials said.
Several other firefighters were badly burned and one was reported missing.
