Indicted Bosnian Serb war criminal Milan Lukic was arrested in Buenos Aires at the request of the International Criminal Tribunal for the former Yugoslavia, an Interpol source told AFP.

In a court indictment, Lukic is accused of forming a paramilitary group in 1992 that worked with local police and military units to exact a "reign of terror" against the Muslim population in the Bosnian city of Visegrad.

In two separate incidents, the indictment says, Lukic and his group forced civilians into homes which they set ablaze, killing at least 140 people.

In the first incident, Lukic and others barricaded a group of Bosnian Muslim women, children and elderly men in a house in which they placed an incendiary device in June 1992.

Lukic and his cousin Sredoje Lukic fired automatic weapons to kill whoever tried to escape through the house's windows. About 70 people were killed in the fire and shooting.

In another incident 13 days later, according to the indictment, Lukic, his cousin and others went to the settlement of Bikavac, near Visegrad, and forced approximately 70 Bosnian Muslims into a house.

"Milan Lukic, Sredoje Lukic, and others then barricaded the exits, and threw several explosive devices into the house which injured the people inside and ignited the house," the indictment says. A fire quickly engulfed the house, killing everyone except one person.
