A wildfire that has destroyed around 3,000 hectares of land in a nature reserve in eastern Belgium since Friday is partly under control, said Belgian Interior Minister Bernard Quintin.

The part of the fire front spreading towards Monschau in Germany is under control, Quintin wrote on X, as well as the front towards the Belgian town of Jalhay.

On Sunday morning the fire front was roughly one kilometre long.

Belgium is also receiving additional help from other European countries to battle the record blaze.

In addition to two firefighting helicopters with large water tanks from the Netherlands, two water-scooping planes from Sweden are expected to be operational from Sunday afternoon, Quintin said.

Firefighters from Germany and Luxembourg are already deployed at the site, local authorities said.

The rugged landscape of the High Fens nature reserve is complicating efforts to tackle the blaze, with few roads providing access and extensive peat bogs making firefighting difficult.

On Saturday, around 600 people had to be evacuated from two Belgian municipalities close to the fire.
