War criminal Slobodan Praljak has died after drinking what he claimed to be poison during a court appearance.

The former Croatian army chief drank from a small bottle and yelled “I am not a war criminal, I oppose this conviction” when his 20-year sentence was upheld by UN judges at The Hague.

The dramatic turn of events, which was broadcast on a video feed, forced the judges to temporarily suspend the hearing, with paramedics seen entering the courtroom.
