Former UN soldiers are suing the Netherlands for damages related to their deployment more than 20 years ago at the town of Srebrenica, where thousands of boys and men were executed in the Bosnian War.
The soldiers were sent on an "impossible mission," lawyers representing the 12 veterans told Dutch news agency ANP on Thursday.
The soldiers were part of a UN peacekeeping unit known as Dutchbat, which was supposed to protect the enclave against advancing Bosnian Serb forces.
In July, Bosnian Serb units overran Srebrenica and Dutchbat capitulated without resistance.
The advance of the Bosnian Serbs resulted in the genocide at Srebrenica - often described as the worst atrocity in Europe since the Holocaust - where more than 8,000 Muslim Bosniak boys and men were executed.
"Dutchbat was sent without appropriate preparation, without sufficient materials and capacity on an impossible mission," the lawyers said.
The veterans haven't been properly compensated for psychological and financial damages resulting from the deployment, according to the lawyers.
