Bosnia has formally asked the UN's top court to review its ruling which cleared Serbia of genocide in the 1990s, Bosnia's Muslim leader has said, according to BBC News.

Bakir Izetbegovic, a member of Bosnia's tripartite presidency, said he was seeking "truth and justice".

Bosnian Serb officials warned the move would trigger a "serious crisis" in the country. In 2007, the International Court of Justice (ICJ) cleared Serbia of direct responsibility for genocide.

The ICJ found only one act of genocide during Bosnia's 1992-95 war - the massacre of about 8,000 Bosnian Muslim (Bosniak) men and boys by Bosnian Serb forces in the town of Srebrenica in 1995.

It was Europe's worst atrocity since World War Two.

The ICJ ruled that Serbia had violated international law by failing to prevent the killings, but absolved it of direct responsibility.

'Serious crisis'

On Thursday, February 23, Izetbegovic told reporters that "the request [for a review] is being submitted at this very moment".

"I think that I am on the path of truth and justice," he added.

The appeal was launched before a 10-year deadline expires on February 26.

Mladen Ivanic, the Serb member of the presidency, said the move should have been made collectively by the tripartite body, where a Bosnian Croat also has a seat.

"I am afraid that we have entered a really serious crisis," Ivanic said.

Meanwhile, Serbia Prime Minister Aleksandar Vucic earlier described Izetbegovic's intentions as "bad" for relations between the two countries.

Following the 1992-1995 war, Bosnia is now an independent state under international administration.

Its three main ethnic groups are Bosniaks (Bosnian Muslims), Croats and Serbs.

Politicians from Bosnia's two semi-independent entities - the Muslim-Croat Federation and the Republika Srpska - have often clashed, triggering political crises.

The powers of the central government in the capital Sarajevo are very limited.
