ISTANBUL — Turkish President Recep Tayyip Erdogan set off on a three-day Balkans tour on Tuesday to try to mediate a crisis that threatens fresh conflict among former Yugoslav states.
Erdogan’s first stop was in Bosnia and Herzegovina, where politicians from the Serb-dominated Republika Srpska — one of two political entities that make up the country — have made calls from the enclave to run its own affairs and form an army.
