After being told once again to sit down, Praljak downs something from a bottle.
Slobodan Praljak, a former Bosnian Croat official who was on trial Wednesday at the International Criminal Tribunal for the former Yugoslavia, has reportedly died after drinking poison.
It could not immediately be confirmed whether Praljak had taken poison, but a court spokesman said he was alive and receiving medical attention.
Croatian Prime Minister Andrej Plenkovic offered his condolences to Praljak's family and said the former general's actions reflected the "deep moral injustice" done to him and the five others whose sentences were also upheld by the appeals judges Wednesday.
Dutch police, an ambulance and a firetruck quickly arrived outside the court's headquarters and emergency service workers, some of them wearing helmets and with oxygen tanks on their backs, went into the court.
The case is the last judgment by the International Criminal Tribunal for the former Yugoslavia (ICTY), established by the United Nations in 1993, before it closes next month.
The crimes Praljak were convicted for stem from the destruction of a 16th century bridge in November of 1993, which the judges said "caused disproportionate damage to the Muslim civilian population".
Praljak was among six former leaders of the wartime "Croat Republic of Herzeg-Bosnia (Herceg-Bosna)" - whose guilty verdicts were confirmed today by the Appeals Chamber.

The prison terms for Prlic (25 years) and Stoic and Praljak (20 years each) remained unchanged.
The bloody 1992-1995 war in Bosnia, in which 100,000 people died and 2.2 million were displaced, mainly pitted Bosnian Muslims against Bosnian Serbs, but also saw some brutal fighting between Bosnian Muslims and Bosnian Croats after an initial alliance fell apart.
More than an hour after the incident, a court guard told Reuters news agency said Praljak was still "being treated".
The original conviction said that late-Croat President Franjo Tudjman was a key member of a plan to create a Croat mini-state in Bosnia. They also overturned some of his convictions, but refused to reduce his overall sentence.
The aim of the scheme was to set up "a Croatian entity that. facilitated the reunification of the Croatian people".
He was originally sentenced to 20 years in jail in 2013.
