BUCHAREST, Romania (AP) — Romania's opera house has apologized after a third show this week was canceled at short notice and warned the public to expect more turmoil as it is rocked by a bitter dispute.

The National Opera of Bucharest expressed its regret Sunday that a ballet was not performed as scheduled "due to a number of individual actions."

Ballet dancer Marina Minoiu said spectators jeered the orchestra, who refused to perform Saturday, and applauded ballerinas who were waiting to dance.

Culture Minister Vlad Alexandrescu announced this week he would appoint a manager "of international standing" to end the turmoil which has involved international ballerina Alina Cojocaru.

Her fiance, the Danish ballet dancer and choreographer Johan Kobborg recently resigned from the opera citing pressure from managers, but Alexandrescu said he will be reinstated.
