(ANSA) - BELGRADE, JAN 5 - The international hacking collective Anonymous claims to have taken down Serbian President Aleksandar Vucic's official personal website. "If he wants to play with fire, then let's begin," Anonymous TV wrote on Twitter today. This afternoon, the website was inaccessible from several European countries for a while. In addition, the website of Serbia's Minister of Defense was briefly unavailable from outside Serbia. On Twitter recently, Anonymous slammed Vucic, calling him "Putin's puppet" and accusing the Serbian leader of destabilising northern Kosovo in order to spark a military conflict. (ANSA).
