The central Belgrade mural of convicted Bosnian Serb war-time military chief Ratko Mladic has been painted over.

In another failed attempt to remove the mural on Monday, an opposition MP and a group of people painted a red heart over the face. Except for the red heart, the mural was painted over in white on Tuesday.

Activists have repeatedly attempted to remove the mural but were prevented from doing so by right-wing groups.
