The man suspected of killing four people at the Brussels Jewish Museum in May has been charged with 'murder in a terrorist context'.
One day after his extradition from France, federal police said that Mehdi Nemmouche had also been interrogated by a counter-terrorist unit.
Nemmouche agreed to his extradition only after he received sufficient guarantees he would not be turned over to a third country. Nemmouche, 29, had fought with Islamic extremists in Syria.
On May 24, a lone gunman walked into the Jewish Museum in the centre of Brussels, unpacked a Kalashnikov rifle, killed four people with a burst of fire, packed up and walked away.
Nemmouche was arrested at a Marseille bus station a few days later carrying weapons resembling those used in the killings.
