Politikilder opplyser til internasjonale medier at Salah Abdeslam, som mistenkes for å ha vært blant dem som stod bak terrorangrepene i Paris den 13. november 2015, er blitt arrestert under en politiaksjon i Brussel-bydelen Molenbeek.
Abdeslam skal ha blitt såret i benet under operasjonen.
This has not been officially confirmed. Shots were earlier heard in the Molenbeek area of Belgium’s capital.
Belgian PM Charles Michel had to urgently leave an EU-Turkey summit in Brussels, a BBC reporter says.
Arrestasjonen finner sted kort tid etter en annen antiterroraksjon i den belgiske hovedstaden.
One man – identified as Algerian national Mohamed Belkaid and linked to the Paris attacks – was shot dead during the raid in the southern Forest suburb.
Officials said they believed as many as two other suspects may have escaped.
