Two French journalists on Thursday told a terror trial in Brussels that Mehdi Nemmouche, the main defendant in the May 2014 Jewish museum murders, had imprisoned and tortured them in Syria.

The journalists who were freed in April 2014 came to the Belgian capital to testify about the character of Nemmouche, a 33-year-old Frenchman who faces a life sentence if convicted of the murders.

"I have absolutely no doubt about the fact that Mehdi Nemmouche who is present here was my jailer and torturer in Syria under the name of Abu Omar," former hostage Nicolas Henin told the trial.
