Three people including a 16-year-old have been charged in southern France on suspicion of planning an 'imminent' terror attack, judicial sources said.
The three - arrested on Friday near the coastal city of Montpellier - were identified as Thomas Sauret, 20; his partner, a 16-year-old minor named only as Sarah; and Malik Hammami, 33.
They were indicted on Tuesday for 'criminal association in connection with a criminal terrorist enterprise', the sources said.
Sauret and his partner were also charged with making and possessing explosives in an organised group.
The case is being handled by anti-terrorism investigators, the sources said.
