Thousands of supporters are protesting the arrest of Ratko Mladic.
The Tuesday’s gathering is the biggest demonstration so far in Bosnia in support of Mladic, arrested last week in Serbia after 16 years on the run. Gathered in Banja Luka, the crowd chanted Mladic’s name, and carried his picture alongside those of Russian Prime Minister Vladimir Putin and President Dmitry Medvedev , whom they consider as their biggest allies.
