WASHINGTON — The Ukrainian parliament agreed with the new Ukrainian president to partially mobilize about half of 40,000 reserve troops.
The crisis erupted after pro-Western protests  gripped the country since late last year, in response to the national government pulling out of a trade pact  with the European Union. After months of protests and international pressure, the national parliament voted to oust  the pro-Russia Ukrainian President Viktor Yanukovich. Russia had denounced the protests ever since they started and accused both the U.S. and European Union of interfering with Ukrainian affairs. After denying an important financial aid package  to Ukraine, Russia sent in troops occupy the Crimean peninsula.
Ukraine has since put its troops on alert  after the Crimean crisis began.
The Ukrainian Secretary of the National Security and Defense Council, Andriy Paruby, informed parliament that 20,000 reserve troops will be deployed within the national armed forces. The other 20,000 troops will be integrated into the recently-created National Guard.
