"Protesters took to the streets as Belarus held a referendum on Sunday to adopt a new constitution that would ditch its non-nuclear status at a time when the country has become a launchpad for Russian troops invading Ukraine. The vote, almost certain to pass under the tightly controlled rule of President Alexander Lukashenko, could see nuclear weapons on Belarusian soil for the first time since the country gave them up after the fall of the Soviet Union. The referendum sparked anti-war protests in several cities, as people chanted "no to war", cars blared their horns in solidarity, and people laid bunches of flowers in the yellow and blue colours of the Ukrainian flag. At least 290 people were detained, rights activists said.
On Sunday, speaking at a polling station, Lukashenko said that he could ask Russia to return nuclear weapons to Belarus.
"If you (the West) transfer nuclear weapons to Poland or Lithuania, to our borders, then I will turn to Putin to return the nuclear weapons that I gave away without any conditions," Lukashenko said."
