Minister of Interior Nebojsa Stefanovic said that the Serbian security services are monitoring the situation related to the radical terrorism on a daily basis and are undertaking all measures to prevent spill over of terrorism from the region.  "Anyone who wants to jeopardize Serbia can expected tough response, because we will not allow anyone to experiment with terrorist attacks," said Stefanovic. When asked to comment on videos that the radical Islamists post on internet, Stefanovic said that these videos are not a surprise for domestic security services. He noted that the Serbian Police earlier warned on the possibility of possible threats to Serbia and the radicalization of individuals, especially young people.
