Albania's opposition Democratic Party says it is disputing the validity of Sunday's local government elections in the cities of Tirana and Durres.

Democratic Party leader former President Sali Berisha said Monday the Socialist Party and the electoral commission had manipulated the voting lists in the two cities to orchestrate a Socialist win. The Socialists have denied the accusations.

Sunday's balloting involved nearly 400 municipalities nationwide. Voter turnout was less than 50 percent. Final vote results have not been released.

The Organization for Security and Cooperation in Europe monitored Sunday's balloting. It is expected to issue a report on Tuesday.
