Chad's ex-leader Hissene Habre has been held down by masked security officers in the courtroom at the resumption of his trial for war crimes in the Senegalese capital Dakar.
Mr Habre had to be forcibly brought to court having refused to attend.
He disrupted proceedings, shouting at the clerk who was reading out a list of names of some of his alleged victims.
Mr Habre is accused of ordering the killing of 40,000 people during his rule in the 1980s, charges he denies.
