MOSCOW – North Korea has advised foreign diplomats to consider evacuating their embassies there, in light of increasing tensions in the area, Russian and British diplomats said Friday. Russia’s foreign minister, Sergei Lavrov, told reporters traveling with him in Uzbekistan Friday afternoon that Moscow was seeking more details about the North Korean statement before making a decision about whether to evacuate. Lavrov said Russia was treating the statement from Pyongyang as a suggestion and not an order.
