Serb leader Boris Tadic arrives in Vukovar

President Boris Tadic has arrived in Croatia, the first Serbian leader to pay his respects to victims of a massacre in 1991.

Mr Tadic arrived in Vukovar on a ferry which crossed the Danube from the Serbian town of Bac and was welcomed by Croatian President Ivo Josipovic.

Vukovar was reduced to rubble by Serb-led Yugoslav army shelling in November 1991.

The event is being seen as an attempt to relax relations between the two countries.
