BELGRADE – Serbian police say five people were killed and at least 20 wounded when a man opened gun fire inside a cafe in the country’s north.

A police statement said the man “entered the cafe and opened fire with an automatic rifle, killing his wife and another woman, then he continued to shoot at other citizens in the cafe.”

Interior Minister Nebojsa Stefanovic visited the scene and was quoted by N1 television channel as saying that the weapon was illegal that and jealousy was believed to be the motive.

The latest incident happened just after midnight in Zitiste, about 80 kilometers from the capital, Belgrade.

Police arrested the alleged shooter, Sinisa Zlatic, born in 1978, and opened an investigation into the killings.

Stefanovic said the attacker tried to flee the scene, but police stopped and arrested him.

“We are all shocked that something like this could happen, since this was a very quiet man who had no police record,” Stefanovic said, according to the state-run Tanjug news agency.

N1 channel reported that the attacker argued with his wife in the cafe, left the building, and returned with a Kalashnikov-type rifle with which he opened fire.

Two people were killed instantly, while three died after being taken to hospital in the nearby city of Zrenjanin, the channel reported.

Police said that seven of the wounded — at least three of whom are minors — are in “very serious condition.”
