SARAJEVO, Bosnia-Herzegovina (AP) — Sarajevo, a religious melting pot throughout its more than five-centuries-long history, would normally be teeming with life this April.

During the war of the 1990s and the years of economic instability that followed, thousands of Sarajevo residents fled to other countries and remained there.
