Russian President Vladimir Putin signed the laws for the adoption of four Ukrainian regions partially occupied by Russia into the Russian Federation.

Axar.az reports citing foreign media.

"Russian President Vladimir Putin signed four federal constitutional laws on the entry of the Donetsk People's Republic (DPR), Luhansk People's Republic (LPR), Zaporizhzhia Oblast and Kherson Oblast into the Russian Federation," the lower house of the Russian Parliament reported. "He also signed the relevant laws for ratification," the State Duma reported.

Earlier this week, both houses of the Russian parliament ratified the treaties to incorporate the four regions into Russia. The contracts were signed in Moscow on September 30.
