Frenchman Mehdi Nemmouche, suspected of killing four people at Brussels' Jewish museum in May, was remanded in custody for a**ther three months on Friday, judicial officials said. Nemmouche, 29, of Algerian origin and who spent more than a year fighting with Islamic extremists in Syria, has been charged with "murder in a terrorist context" after an Israeli couple, a French woman and a Belgian were shot dead at the museum in central Brussels. The court buildings in Brussels were under heavy security for the hearing, highlighting the sensitivity of the case which shocked the country and dismayed its Jewish community. One of the lawyers, Sebastien Courtoy, said there was a major problem with prosecution in that "there is ** direct proof of the clear presence of Nemmouche at the scene".
