Motherland authorities surrounded the speaker's lectern and ploughed the voting equipment in the chamber in order to intervene and suspend the debate.
The fight cracked out after the Regions members moved to push the Opposition party members away from the lectern and voting equipment.
Members from both the parties used shoes, fist and chairs to ensure melee in the parliament and exchanged non-parliamentary words that maintained ruckus and chaos for five minutes.
Security guards made no effort to stop the fight. Two party members from Motherland, Ihor Gnatkevich and Vasyl Kravchiuk were badly hurt and medical workers carried them on a stretcher to hospital.
