UNITED NATIONS (AP) _ The U.N. Security Council unanimously agreed to the selection of Balkan expert Wolfgang Petritsch of Austria as the international community's top civilian administrator in Bosnia.

By a vote of 15-0 Tuesday, the council welcomed Petritsch's designation as high representative by the steering board of the Peace Implementation Council, which oversees implementation of the 1995 Dayton peace accord that ended the 2 1/2 year war in Bosnia.

Petritsch replaces Carlos Westendorp of Spain, who has been elected to the European Parliament.

The Security Council paid tribute to Westendorp's work and reaffirmed the importance of the high representative in pursuing implementation of the Dayton agreement.
