When a fire breaks out in the Bosnian city of Mostar, Sabit Golos, a veteran firefighter, knows that he does not have to worry unless the flames take hold on the Muslim side of what, from 1992 until 1994, was the front line in a vicious ethnic conflict.
That is because Mostar, though long at peace, has two separate fire brigades, one made up mostly of Muslims like Mr. Golos, who are responsible for putting out fires on the east side of the old front line and a second one staffed by Catholic Croats who douse flames on the other side.
