Estonia will close all border crossings with Russia from December 1 after an incident with an attempt to set fire to a defense plant, Foreign Minister Margo Tesa said. According to the head of the Ministry of the Interior of Estonia Igor Trau, the government will decide to close the border with Russia next week. He added that the decision could be temporary or permanent. Earlier, eight citizens of Latvia were arrested in Estonia after trying to establish the defense company "Tarau Kitsom" in the municipality of Vimisi on November 14. Estonian authorities accuse Russia of involvement in the incident without evidence.
