The trial in absentia of four former high-ranking Croatian Air Force officers accused of bombing a convoy of Serb refugees in August 1995 should start at the end of December in Belgrade.
President Zoran Milanovic repeated on Wednesday that Serbia should "watch its actions" and that he was only asking for "a fair relationship" between the two countries, adding that Croatia could have indicted Serbian President Aleksandar Vucic but made a political decision not to do it.
