MOSCOW — The North Korean government on Friday advised Russia and other countries to consider evacuating their embassies in Pyongyang amid rising tension there, Russia’s foreign minister said.

British officials said that they had received a similar communication, but that there were no immediate plans to evacuate the British Embassy.

Analysts in Russia and South Korea suggested that the North’s advisory was not an indication that Pyongyang was considering military action but was instead part of an unrelenting drumbeat of threats calculated to frighten the United States and its Asian allies, possibly to force concessions including much-needed aid.

“I don’t think they are doing this because they think there is going to be a war,” said Kim Yong-hyun, a professor of North Korean studies in Dongguk University in Seoul, South Korea. “Rather, this is part of a calculated, psychological campaign to increase a sense of crisis and get international attention.”
