Thursday's briefing was to include discussions of the US' global missile defense system. According to Yemelyanov, the general staff of the Russian Armed Forces planned to participate in the briefing under the direction of chief adviser of the general staff of the Russian armed forces and first Deputy Defense Minister of Russia Lieutenant General Tretyak.
"However, the local authorities refused to issue entry visas to the entire delegation, including the delegation head, [Tretyak]," Yemelyanov said.
The US Department of State has declined to comment on its denial of visas for Russian General Staff officials, a department spokesperson told Sputnik later on Thursday.
"Since visa records are confidential under the Immigration and Nationality Act, we are not able to discuss individual visa cases," the spokesperson said.
