Ukrainian Security Service (SBU) Head Vasyl Hrytsak has suggested legislatively prohibiting Ukrainian lawmakers, politicians, and public figures from visiting Russia.

"It will clearly help us in our work. I support the president's initiative. I would go even further, I would introduce a legal prohibition and criminal liability for visits to the aggressor state by lawmakers, politicians, and public figures," Hrytsak said in Kyiv on Saturday, replying to reporters' request to comment on the decision to impose biometric control measures on Russians entering Ukraine in 2018.

Ukrainian President Petro Poroshenko's order on introducing biometric control for foreigners, including Russian citizens, entering Ukraine in 2018 was published in the Uriadovy Kurier governmental newspaper on September 2 and, therefore, entered into effect.
