BELGRADE, Serbia (AP) — Serbia's police chief says Prime Minister Aleksandar Vucic has been moved to a safe location after a large of cache of weapons was found near his family house near Belgrade.

Interior Minister Nebojsa Stefanovic said Saturday that a trunk found in a forest by the house held an anti-tank rocket, hand grenades and sniper rifle ammunition.

Stefanovic says the location is "ideal" for an assassination attempt and that he was afraid for Vucic's safety. He says it was not the first time the prime minister was a potential target, but did not elaborate.

Stefanovic says "it is highly unusual" for such weapons to be discovered near a place where cars have to slow down before entering or leaving Vucic's house.

He says it is not "a naive" incident.
