The leaders of former Balkan foes Serbia and Bosnia have pledged to boost fragile postwar ties shaken earlier this month on the 20th anniversary of the Srebrenica massacre of 8,000 Muslims by Bosnian Serbs.

Bosnia's three-member presidency and Serbia Prime Minister Aleksandar Vucic held a hastily-called meeting Wednesday to underscore a bid to put the past behind and work together for a warless future in the volatile region.

Tensions soared after Vucic — a former Serbian nationalist — was attacked during the July 11 commemoration ceremonies in the eastern town. Bosnian Muslims also have been angered by Serbia's refusal to call the massacre genocide.

Muslim leader Bakir Izetbegovic says "we have agreed to do everything to improve relations so that evil will never repeat itself."
