One person has been killed and at least four injured in a suspected gas blast at a sports centre near Belgium's border with France.

Chimay police chief Pierre Maton said the blast was most likely to have been a gas explosion and an investigation into the cause was continuing.

The blast in the town, 75 miles south of the capital Brussels, happened just after midnight local time.

The area was cordoned off, but the damage was not as serious as initially feared.

Windows were blown out of the two-storey building and one corner of the structure was badly damaged, but there was no major collapse.

Firefighters were clearing the rubble and securing the building early on Friday.

Police said they believed they had retrieved all the people from the rubble.

Chimay has a population of about 10,000 and is known for one of Belgium's most famous breweries.
