(CNN) A prominent Kosovo Serb politician, Oliver Ivanovic, was shot dead outside his party offices Tuesday morning, halting talks between Kosovar and Serb delegates that had been set to resume that day.

Ivanovic was shot at least five times outside his office in the Serb-run Kosovar city of Mitrovica, doctors told Serbian State TV RTS.

Emergency services were notified of the attack at 8.17 a.m (2.17 a.m. ET). Ivanovic was transferred to hospital and resuscitated for 45 minutes before doctors confirmed him dead at 9.15 a.m (3.15 a.m. ET).

Ivanovic, the 64-year-old head of the Kosovo Serb Freedom, Democracy, Justice party was due to attend EU-mediated talks between delegates from Kosovo and Serbia in Brussels. The talks are aimed at normalizing relations between Kosovo and Serbia.

Kosovo declared independence from Serbia 10 years after the bloody conflict between Serb forces and Kosovar-Albanian rebels. Serbia does not recognize Kosovo as an independent country.
