BEIRUT -- Lebanese police and military officials say a roadside bomb has targeted a convoy of U.N. vehicles in the country's south killing two Italian U.N. peacekeepers and wounding at least three people, the ANSA news agency reported.

Friday's explosion happened in Sidon. A U.N. peacekeeping force in Lebanon is deployed in southern Lebanon to monitor the border with Israel. The force had no immediate comment.

The Lebanese officials spoke on condition of anonymity because they were not authorized to speak publicly.

The last such incident was in January 2008, when a roadside bomb struck a U.N. vehicle traveling along the coastal highway south of Beirut, lightly wounding two peacekeepers.

The deadliest attack was in June 2007, when six Spanish peacekeepers died when a bomb hit their armored personnel carrier near the Israeli border.
