SIMFEROPOL, Ukraine — Russian armed forces effectively seized control of Ukraine’s Crimean Peninsula on Saturday, as President Vladimir V. Putin had the Russian Parliament grant him broad authority to use military force in Ukraine in response to deepening instability there.
Russian troops stripped of identifying insignia and military vehicles bearing the black license plates of Russia’s Black Sea force swarmed the major thoroughfares of Crimea and occupied major government buildings, closing the main airport and solidifying what had been a covert effort to control the largely pro-Russian region of Ukraine.
In Moscow, Mr. Putin convened the upper house of Parliament to forcefully denounce President Obama and obtain authorization to protect Russian citizens and soldiers stationed in Crimea as well as other parts of Ukraine.
