VALPARAISO — Chile on Sunday mobilised its military to help evacuate thousands of people in its port city of Valparaiso threatened by a huge, out-of-control forest fire that has already killed four people and destroyed 500 homes.

President Michelle Bachelet declared the massive blaze threatening the city — whose historic center is a protected Unesco heritage site — a disaster zone, permitting the armed forces to step in.

"This is the worst catastrophe Valparaiso has ever seen," the regional government administrator, Ricardo Bravo, told local reporters.

"We have four people dead — three men and a woman," Interior Minister Rodrigo Penailillo told Radio Cooperativa, giving a provisional death toll.

More than 3,000 people have so far been evacuated from their homes on the heights above Valparaiso, a city of 270,000 people which lies on the Pacific coast 110km northwest of the capital, Santiago.

The massive tongues of flame were advancing down the slopes of the city towards its port and heritage-listed centre, driven by strong winds. Many residents overnight watched, helpless, from distant vantage points as the hills burned bright red. Thick smoke clouded the sky.

Hundreds of firefighters, including ones dispatched from the capital, were hopelessly outmatched in their battle to limit the spreading disaster. They were forced to retreat time and again as flames reduced homes to cinders, a wall of red towering above them.

The city is spread out over more than 40 hills, hindering emergency vehicle traffic.

"My brother’s house was entirely burnt. We had only finished it two weeks ago. We tried to save something but it was truly an inferno," one resident, Cristobal Perez, told the Chilevision television network.

"I started to become overcome by the smoke along with my two dogs. It was terrible — impossible to breathe," another resident told the channel.

The vast blaze has caused cuts to power and drinking water in many areas of Valparaiso.

The cause of the fire, which began in woodland near the city late on Saturday, was being investigated.

Authorities have set up nearly a dozen shelters to take in those evacuated. Pets were not being allowed in the shelters and animal welfare organisations said some owners were therefore choosing to sleep in the street with their dogs or cats.

Mr Penailillo went to Valparaiso and said the disaster decree Ms Bachelet issued on Saturday activated an "exceptional" constitutional process allowing the military to be called in to help.

The navy, which has a major base in the port city, immediately responded by taking over security. It deployed uniformed personnel into the streets to maintain order and to help with the evacuations.

Valparaiso is one of Chile’s most important ports. It lived its era of glory from the mid-19th century to the early 20th century as a stopover point for ships steaming down South America and to round its southern tip into the Atlantic Ocean.

The centre of the city still features the many coloured houses dating from that period, built by European immigrants. Its cobbled streets and funicular trams running up near-vertical rails supported its 2003 listing as a Unesco-protected heritage site.

Fires occur frequently in central Chile, where summer sends temperatures soaring. In February 2013, about 105 homes were destroyed in Valparaiso, affecting 1,200 people, after a 27-year-old man started a blaze.
