The Minister of Internal Affairs of Serbia (MIB), Ivica Dačić, said on Tuesday that he has received official information about a person who allegedly sent threatening messages at the “Nikola Tesla” airport in Belgrade, in the Serbian embassies in Germany and Austria, as well as in the Belgrade Center for Security Policy.

“Regarding the threatening messages received via e-mail, the Ministry of Internal Affairs of Serbia has received official information that the person in question is Denis Krasniqi (born in 1998) from Switzerland, whose parents are from Kosovo”, says the announcement of the Ministry of Internal Affairs.

Dačić said that Krasniqi “is currently in Kosovo” and that he “has been ordered” to appear before the Swiss police “immediately after returning to Switzerland.”

Earlier in the day, the Minister of Foreign Affairs of Serbia, Marko Duric, told Pink television that the Serbian embassies in the two main European capitals have been threatened in the last 24 hours to be the “target of terrorist attacks”.

He added that he does not want to give details without consulting the security authorities, because “I don’t want the situation to worsen”.

Duric said that on Tuesday morning security measures were increased in some of the diplomatic offices and consular missions of Serbia in Europe.

Radio Free Europe has contacted the Ministry of Foreign Affairs of Kosovo regarding Marko Duric’s statement, but has not received a response.
