Aleksandar Vucic has commented on the insults made at the expense of Milena Ivanovic, to say that he "never understood that kind of insanity and hatred."

The president reacted after one of the leaders of the opposition Alliance for Serbia, Zeljko Veselinovic, referred to the widow of Oliver Ivanovic, a Serb politician from Kosovo who was gunned down in Mitrovica North a year ago, as a "she devil."

In a tweet that has since been removed, Veselinovic said Milena Ivanovic was frequenting nightclubs in the capital and missed her late husband's one-year memorial service.

Speaking in Leskovac on Monday, where he attended the opening of an Aptiv Packard factory, Vucic described Ivanovic as a "brave woman" and added that the Interior Ministry must check whether it is necessary to carry out security assessment and protect her and her son.

Commenting on announcements out of Pristina about the possibility of introducing new measures that include banning vehicles from Serbia in Kosovo, Vucic assessed that Pristina will weaken its international position, "whatever it does."

"We will always find plenty of ways to help our people in Kosovo and Metohija. We will go through all the troubles together and we will successfully overcome them," Vucic said.
