THE HAGUE, Netherlands (AFP) — In shocking live scenes, a Bosnian Croat war criminal took his own life yesterday in front of UN war crimes judges, apparently drinking poison just after they upheld his 20-year jail term for atrocities committed during the 1990s Balkans conflict.

Slobodan Praljak, 72, died in hospital, after drinking from a small brown glass bottle in full glare of the cameras at the International Criminal Tribunal for the former Yugoslavia (ICTY), officials said.

The unprecedented drama came as judges handed down their very last verdict at the court in the appeal case of six Bosnian Croat political and military leaders.

Praljak, a former military commander of a breakaway Bosnian Croat statelet, shouted out angrily: “Praljak is not a criminal. I reject your verdict.”

Standing tall, with a shock of white hair and beard, he then raised a small brown bottle to his lips, and tipped it into his mouth. The hearing was quickly suspended as Praljak’s lawyer interjected: “My client says he has taken poison.”

The stunning events caused a shockwave in Croatia, and cast a cloud over what should have been a successful end to the ICTY, which closes next month more than two decades after being set up at the height of the 1992-1995 Bosnian conflict.

Immediately after sentence was passed Praljak “drank a liquid while in court and quickly fell ill”, ICTY spokesman Nenad Golcevski told reporters. He could not confirm what was in the bottle.

As emergency crews rushed to the tribunal efforts were made to give him medical treatment and he was “transported to the hospital where he passed”, Golcevski added.

The courtroom has now been secured as a crime scene by Dutch investigators, who will be leading the probe into Praljak’s death.

Among the questions to be answered will be how he managed to evade tight security to smuggle the bottle into the tribunal.

And if the liquid was indeed poison or noxious, how did he acquire it in the UN detention centre in The Hague where he was being held?

Croatia’s Prime Minister Andrej Plenkovic slammed the “injustice” of the UN tribunal and expressed his condolences.

“His act, which we all unfortunately witnessed today (yesterday), speaks mostly about the deep moral injustice towards six Croats from Bosnia and the Croatian people,” he told reporters.

Praljak’s act demonstrated “what sacrifice he was ready to make” to show he was “not a war criminal”, said Dragan Covic, the Croat member of Bosnia’s tripartite presidency.

“It is a humiliation of this institution which has existed since 1993.”

Late yesterday, candles were lit in Mostar by Bosnian Croats and other residents in tribute to the late general.

It is not the first time that defendants have taken their own lives at the ICTY. Former Croatian Serb leader Milan Babic killed himself in his cell at the UN detention centre in 2006, after another Croatian Serb, Slavko Dokmanovic, in 1998.

And former Serbian President Slobodan Milosevic was found dead in his cell in 2006 from natural causes before his trial could be completed.

In the complex ruling, the judges upheld the jail terms against all six defendants, including a 25-year sentence imposed on Jadranko Prlic, the former prime minister of the breakaway Bosnian Croat statelet, known as Herzog-Bosna.

Praljak had been specifically charged with ordering the destruction of Mostar’s 16th-century bridge in November 1993.

But in their ruling, the judges allowed part of Praljak’s appeal, saying the bridge had been “a military target at the time of the attack”. But they refused to reduce his overall sentence.

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.

The appeal judges said all six men, who had been found guilty of seeking to remove Bosnian Muslims from the territory, “remained convicted of numerous and very serious crimes”.

In statements sure to anger Zagreb, the judges upheld the original trial finding that the men had been part of a joint criminal enterprise whose “ultimate purpose was shared” by late Croatian President Franjo Tudjman, and other leaders.

The aim of the scheme was to set up “a Croatian entity that… facilitated the reunification of the Croatian people”.

Following the verdict, Croatian President Kolinda Grabar-Kotarovic interrupted an official visit to Iceland to rush home.

Terms ranging from 20 to 10 years were also upheld against the four other defendants.

Yesterday’s verdict came a week after the judges imposed a life sentence on former Bosnian Serb military commander Ratko Mladic.

His judgement had also descended into confusion when he accused the judges of lying and had to be dragged away into a nearby room.

The ICTY closes its doors on December 31, having indicted and dealt with 161 people.
