AMSTERDAM, Nov 27 (bdnews24.com/Reuters) - Families of Srebrenica massacre victims have cleared a legal hurdle in their lawsuit against the Dutch state and the United Nations, which they argue allowed the killing of thousands of Muslims, their lawyers said.

A court in the Hague ruled the case could proceed, dismissing pleas by public prosecutors that it should be dropped after the United Nations invoked its legal immunity and said it would not take part.

In 1995 Bosnian Serb forces massacred 8,000 Muslim men and boys from Srebrenica, a town declared a safe area and guarded by a Dutch army unit serving as part of a larger UN force.

Lawyer Marco Gerritsen, representing the victims' families, said on Tuesday the court had supported their argument that the UN could not be granted automatic immunity.

"The UN has the duty to prevent genocide. An appeal to immunity in a case of genocide, as in the Srebrenica drama, is irreconcilable with the UN's own objectives and its international obligations," he added in a statement.

Victims' families launched the suit against the Netherlands and the UN in July, arguing the Dutch were to blame for the massacre because they refused crucial air support to their own troops defending the Bosnian town. Lightly armed Dutch soldiers were forced to abandon the enclave to Bosnian Serb forces who took away and massacred Muslim men and boys who had relied on protection from the Dutch troops, their families say.

Former Bosnian Serb leader Radovan Karadzic and former Bosnian Serb Army chief Ratko Mladic, both wanted by the UN war crimes tribunal in The Hague on genocide charges over Srebrenica, are still on the run.

Dismayed by the failure to bring to justice the two chief suspects, victims' families say they have turned to a Dutch court for recognition and redress for the tragedy.

The Dutch state has always said its troops were abandoned by the UN which gave them no air support, but public documents show a network of Dutch military officials within the U.N. blocked air support because they feared their soldiers could be hit by friendly fire, the families' lawyers said.

The Dutch government led by Wim Kok resigned in 2002 after a report on the massacre blamed politicians for sending the Dutch UN troops on an impossible mission.

"The Srebrenica women have got a fair chance to proceed agaist the United Nations," lawyer Semir Guzin told Reuters in Bosnia.
