Serbian President Aleksandar Vucic says Belgian Prime Minister Charles Michel "presented some new proposals concerning Serbia's European path."

But, the president told a joint news conference with Michel in Belgrade on Tuesday - "I cannot say more about those proposals until they become a part of EU policy, and until some other factors agree with them."

Vucic observed only that the said proposals "could be interesting in the future."

A Brussels court has sentenced Serbian nationals Veselin Vukotic, Andrija Draskovic and Bozidar Spasic to life imprisonment for the murder of Kosovo human rights activist Enver Hadri in Brussels 26 years ago.

The jury handed maximum jail terms to the three men, sentencing Vukotic and Draskovic as the perpetrators and Spasic as the mastermind of the killing.
