Firefighters are working to contain a forest fire in the southeast of the Netherlands on Tuesday after it spread overnight across 100 hectares (247 acres), authorities said.
The blaze started around noon on Monday in a nature reserve near Oostrum in Limburg province, close to the German border.
Changing and strengthening winds helped the fire spread rapidly, while the blaze remained out of control early Tuesday, provincial authorities said.
About 300 emergency workers battled the fire overnight, with firefighting helicopters scheduled to resume operations on Tuesday morning.


A nearby campsite was evacuated, while train services through the area were suspended.
Provincial authorities warned that dry conditions could allow fires to spread quickly through nature reserves but did not say what caused the blaze.
The fire is the latest in a series of wildfires affecting western Europe following a period of extreme heat and drought.
Several European countries are experiencing severe drought, with dried-up rivers, water restrictions and widespread wildfires reported after an unusually intense heatwave in June.
Scientists have linked the worsening drought conditions to human-driven climate change, which is increasing moisture loss from soil, lakes and rivers and raising the risk of extreme drought
