KYIV, Ukraine (AP) – Russian President Vladimir Putin has signed laws absorbing four Ukrainian regions into Russia, a move that finalizes the annexation carried out in defiance of international law. Earlier this week, both houses of the Russian parliament ratified treaties making the Donetsk, Luhansk, Kherson and Zaporizhzhia regions part of Russia. The formalities followed Kremlin-orchestrated “referendums” in the four regions that Ukraine and the West have rejected as a sham.
