By Daria Sito-Sucic and Maja Zuvela SARAJEVO (Reuters) - The president of Bosnia's autonomous Muslim-Croat federation and 19 others were arrested on Friday in an anti-corruption probe that also targeted the offices of the regional government, a spokesman for the state prosecutor said. The raid on Zivko Budimir's Sarajevo office and the regional government in the southern town of Mostar is the most high-profile anti-graft operation in Bosnia since independence more than two decades ago.

Serbia's nationalist President Tomislav Nikolic on Thursday personally apologised for the first time for the 1995 Srebrenica massacre of 8,000 Muslims, but stopped short of calling it genocide. "I kneel and ask for forgiveness for Serbia for the crime committed in Srebrenica," Nikolic said of the slaughter, the worst atrocity in Europe since World War II. Srebrenica "is a synonym for a grave crime committed by some of my people," Nikolic said in an interview aired on Bosnian national television, parts of which were earlier released on YouTube.

Thirty-five people, including seven policemen, were injured in inter-ethnic scuffles between Bosnian Serb and Muslim football fans, police and hospital sources said Thursday. A police source added that 62 football supporters had been detained. Police said about a hundred, mostly Muslim, fans of Zeljeznicar Sarajevo and Serb supporters of Borac Banja Luka, clashed in the central Bosnian town of Donji Vakuf Wednesday while on their way to respective team matches.
