(ANSA) - BELGRADE, JAN 14 - European MEPs expressed concerned about an alleged case of wiretapping of Russian opposition leaders that might have taken place in Belgrade last year. According to the Russian opposition politician Vladimir Kara-Murza, members of the Russian opposition were wiretapped during a meeting in Belgrade in May 2021. Subsequently, the Serbian Interior Minister Aleksandar Vulin handed over the transcripts of the talks to Moscow, the local outlet Nova reported on Wednesday, confirming previous reports. Vulin denied the accusation and said he would sue Kara-Murza, the regional television N1 summarised. "I am shocked with the news of wiretapping Russia opposition leaders in Belgrade and its delivering to Russia intelligence service," MEP Viola von Cramon (Greens) said on Twitter. Serbia "must choose whether it wants to truly transform itself and join the European Union, or further align with the autocrats from Moscow and Beijing," von Cramon added. "We are appalled by this disturbing news. Serbia as a EU candidate country has to uphold human rights, but here it is collaborating with an autocratic regime in the persecution of Russian opposition," the Socialists and Democrats Group in the European Parliament said on Twitter on Wednesday.
