Russian ambassador Pavel Kuznetsov was summoned to the Finnish Foreign Ministry after the Ministry of Defense of Finland suspected a Russian plane of violating Finnish airspace,as stated in the message of the Finnish Foreign Ministry on Twitter.
"The Russian Ambassador was informed about the alleged incident with a request for clarification," the message says.
According to the Finnish Defense Ministry, the incident refers to a passenger or cargo Tu-154. The Finnish border service launched an investigation into the incident.
In early November, the National Armed Forces of Latvia reported that two Russian Su-27 fighters were spotted near the state sea border.
In late November, the Pentagon accused a Russian Su-30 fighter of the "unsafe" interception of the US P-8 Poseidon patrol anti-submarine aircraft in the skies over the Black Sea. According to the Pentagon, the Su-30 flew 50 feet (15.2 m) from the P-8 Poseidon. "Unsafe actions can cause serious harm and injury to all air crews involved in the incident," the Pentagon noted.
In response, the Russian Defense Ministry stated that the Su-30 "helped the American colleagues avoid an international scandal that would have been caused by a violation of the Russian border by American side."
