The media were prohibited from attending new Moscow Mayor Sergei Sobyanin's first session in the Moscow City Hall on Tuesday.
Security at the City Hall in downtown Moscow said they had been ordered not to allow media into the building as of October 26.
"We were told that journalists were not allowed in. It is still unclear whether this is a permanent measure or not," a RIA Novosti correspondent said.
Former Moscow Mayor Yury Luzhkov, sacked by the Russian president in September, usually permitted the media to attend his sessions, which he traditionally held at 10:00 a.m. Moscow time (6:00 GMT) on Tuesdays.
Sobyanin, who was sworn into office by President Dmitry Medvedev last week, is holding his first session at 11:00 a.m. Moscow time. The agenda includes discussion of Moscow's electricity supplies.
