Serbia's president has canceled a scheduled trip to Bosnia amid a diplomatic dispute over the arrest in Switzerland of a former Bosnian Muslim commander on a war crimes warrant from Belgrade.

Tomislav Nikolic canceled the trip to Sarajevo scheduled for Tuesday at the request of the Muslim Bosniak member of Bosnia's tripartite presidency, Bakir Izetbegovic, who said the visit wouldn't have contributed to the improvement of "good neighborly relations."

Izetbegovic's request followed the arrest last week in Switzerland of Naser Oric, the commander in Srebrenica during Bosnia's 1992-95 war.

Swiss authorities arrested Oric on an extradition request from Serbia, which claims he killed Serb civilians prior to the July 1995 Serb attack on Srebrenica when more than 8,000 Muslim men and boys were killed.
