BELGRADE, Serbia (AP) — A man's body has been pulled from a swollen river in southwestern Serbia and rescuers are searching for another man, state television said Friday, as floods across the Balkans closed down schools, hampered traffic and soaked homes and farmland. The floods this week in Serbia, Bosnia, Montenegro, Albania and Kosovo have been triggered by heavy rainfall and unseasonably warm weather. Temperatures dropped in many areas on Friday as rain turned into snow.
