MOSCOW: Russia doesn't really need diplomatic ties with the West after it imposed sanctions on Moscow over what he called Russia's military operation in Ukraine, former president and top security official Dmitry Medvedev said on Saturday.

Medvedev, writing on social media, said it was time to "padlock the embassies."

He said Moscow would continue its operation in Ukraine until it achieved goals defined by President Vladimir Putin.
