Belgrade, Serbia CNN —Serbians are reeling and demanding answers after two mass shootings in less than 48 hours left multiple people dead, with widespread calls for tough action to prevent any further repeat of such tragedies. You could never dream that this would happen here,” Belgrade resident Marko Kovacevic told CNN. “This is the worst thing that happened in Serbia since the bombing in 1999,” another resident, David Stevens, told CNN at a vigil in Belgrade. The murderer had no empathy or remorse,” he told CNN in an interview on Thursday. His deputy, Milan Pašić, told CNN his boss had offered his resignation, but it was not clear if it would be accepted.
