The protest was started by members of the Svoboda party, which has a handful of seats in the Ukrainian Parliament.

Earlier this year, the Ukrainian government announced that it would be transferring powers to separatist regions. This truce with the pro-Russian separatists ended a long conflict that left over 6,000 people dead. Many Ukrainians rejected the move, claiming it threatens the country's sovereignty and independence.

Minister Avakov said that over 30 people have been detained by officials and blames Svoboda leader Oleh Tyahnybok for causing the protests.

Former Prime Minister Yulia Tymoshenko stated that the changes brought by the truce were "not a road to peace and not a road to decentralisation."

She went on to add, "This is the diametrically opposite process, which will lead to the loss of new territories."

Parliament speaker Vladimir Groisman said he doesn't think that the recent changes will make Ukraine a Federalist state. He stated, "There is no hint of federalism. Ukraine was, is and will be a unified state."

The rebels and the Ukrainian army forces have been going back and forth all summer, but will suspend the violence on Sept. 1 because of the first day of school for kids.
