BRASILIA: A forest fire was burning out of control Sunday across a big swath of national park very near Brazil`s capital Brasilia, management of the park told AFP.

More than 140 firefighters were battling the blaze, which was suspected to have been deliberately started in the dry brushland of the park, popularly known as Agua Mineral.

Park management said no one had been hurt in the fire and no private property was at risk so far.

The 30,000-hectare (74,000-acre) park is located just northwest of the capital, a couple of kilometers (miles) from the nearest city suburb, and around 12 kilometers (eight miles) from the government`s main ministry buildings.
