Russia has begun mass production of mobile bomb shelters that can protect against a variety of man-made threats and natural disasters including radiation and shockwaves, the emergency ministry's research institute said. It can give some protection against radiation, shrapnel, debris and fires and can be deployed in Russia's vast northern permafrost, according to the state institute. The institute did not link the move to any current crisis, though the announcement came just as the administration of U.S. President Joe Biden agreed to allow Ukraine to fire American long-range missiles deep into Russia.
