Estonia will temporarily close its checkpoint with Russia in Narva for the weekend, reported DPA, quoted by BTA.
The police and the border services argued for the closure of the border point by stating that the border checks on the Russian side are significantly delayed.
As a result, people who wanted to cross the border had to wait for hours the day before and yesterday to be let through.
Other checkpoints will not be closed and entry into Estonia from Russia will remain possible, DPA states.
According to the Estonian authorities, on the other side of the border crossing "Narva-Ivangorod" long queues have formed for the first time. Footage online showed hundreds of people, some with luggage, waiting at the border. The city administration of Narva has installed mobile toilets and organized the distribution of water for those waiting.
Estonian Interior Minister Lauri Laanemets said he had no information as to why Russian border guards were working so slowly.
Meanwhile, Washington announced economic sanctions against 12 executives at Russian company Kaspersky Lab after it banned the use of its antivirus software in the US on Thursday, accusing the cyber security giant of being close to Russian authorities - something that the company denies, reported France Press, quoted by BTA.
The sanctions are "in response to continuing cybersecurity risks," the US Treasury Department said in a statement.
The US assets of 12 of the company's development, human resources and communications executives have been frozen, along with those of the entities they directly or indirectly control. They are also prohibited from doing business in the US under sanctions imposed by the Office of Foreign Assets Control, which is part of the US Treasury Department.
State Department spokesman Matthew Miller said that Kaspersky Lab's "cybersecurity products and solutions" provide broad access to files" on the "computers on which the software is installed".
However, he added that the company is under the jurisdiction, control or direction of the Russian government, which could use this privileged access to obtain sensitive data, including personal information, or circumvent information security measures.

The spokesman warned that this posed an "unacceptable risk to US homeland security or /.../to Americans".
"Kaspersky Lab" is one of the world's leading companies in the field of cyber security.
In a statement sent to AFP, the company called the US Treasury Department's decision "unfounded and baseless".
"Neither Kaspersky Lab nor its management team have ties to any government, and we believe that the Office of Foreign Assets Control's allegations are pure speculation, lacking any concrete evidence of threat posing a danger to US national security," the company said.
On Thursday, the US Commerce Department announced that the Russian company will no longer be allowed to sell its software in the US or to US citizens in other parts of the world, nor to provide updates to software already in use.
However, "Kaspersky Lab" will be allowed to carry out certain activities until September 29 to give customers time to find an alternative.
The US accuses the company of being close to Russian authorities, which it strongly denies, insisting it has "repeatedly demonstrated its independence from any government" and stating that the US "has ignored this evidence".
In a statement "Kaspersky Lab" condemns the decision, "taken based on the current geopolitical climate and theoretical fears", which "favors cybercrime". She has been defending herself against such accusations for years, notes AFP.
The company has indicated that it intends to challenge the US authorities' decision in court.
