KIEV, July 21 /TASS/. Dmytro Yarosh, the leader of Ukraine’s Right Sector extremist movement, told his supporters at a rally (the so-called popular assembly) on Tuesday that the Right Sector was starting the creation of "revolutionary committees" that would be responsible for holding a referendum on no-confidence to the Kiev government in all parts of Ukraine.

According to various estimates, from 3,000 to 6,000 Right Sector activists took part in the rally held on Kiev’s Independence Square.

"Work to set up emergency headquarters to organize a referendum will start in all parts of Ukraine as of tomorrow," Yarosh said on Tuesday.

According to him, questions of legalization of voluntary battalions and the imposition of martial law in Ukraine will also be put to a referendum.

"The first thing is no-confidence in the ruling power, in all branches of power; people should express their attitude to what’s going on in the state," Yarosh said.

He also called for imposing a blockade on the self-proclaimed Donetsk People’s Republic and Luhansk People’s Republic in eastern Ukraine.

"A total and all-embracing blockade of the occupied territories is necessary," Yarosh stressed.

The Right Sector has also threatened the Ukraine authorities with parallel elections.

"The authorities should know that if they do not suit the people, they should go. If we fail to call a referendum, we are going to create our own Central Electoral Commission and vote separately across Ukraine," Yarosh said.

Yarosh also believes that time has come to force President Poroshenko to resign and disband the government and Verkhovna Rada (parliament).

US Ambassador to Ukraine Jeoffrey Pyatt, who visited Uzhgorod, Western Ukraine, on Tuesday condemned the Right Sector’s actions in Ukraine’s Trans-Carpathian region and said that the use of force and weapons was the prerogative of the Ukrainian government, army and law enforcers.

Right Sector has been banned as an extremist organization in Russia.
