The option of engaging Collective Security Treaty Organization (CSTO) forces in the special operation in Ukraine is not considered, Russian presidential spokesman Dmitry Peskov told reporters Monday, according to RIA Novosti.

"No, that option is not being considered," Peskov told reporters when asked if the Kremlin was considering the option of engaging CSTO forces in the Russian special operation in Ukraine.

To note, Armenia also is a member in the Collective Security Treaty Organization.
