Eight Serb men suspected of taking part in looting, expulsions and killing of civilians during the country's 1992/95 war have been detained by p olice in Bosnia .
One of the arrested men is suspected of gunning down 20 Muslim civilians, including women and children, in a barn where they had been hiding from the Serb soldiers.
The men were arrested in the eastern town of Rogatica, where the alleged crimes were committed in September 1992, the prosecutor's office in Bosnia said .
Some 100,000 people were killed in the Bosnian war that broke out when the country joined several republics of former Yugoslavia and declared independence.
The well-armed Bosnian Serb minority opposed the move and took up arms in its attempt to carve out parts of the country by expelling and killing non-Serbs.
