Ukrainian sources reported the possible use of the RS-26 Rubezh intercontinental ballistic missile by the Russian army. According to them, the strike could be carried out today, and the missile will probably be equipped with a non-nuclear charge. There have been no official statements from Russia on this matter yet. 

The RS-26 missile is fast and powerful, its warhead weighs up to 1,2 tons. If the launch does take place, the strike could come from the East, presumably from the Astrakhan region.

The exact type of missiles and their number remain unknown, but Ukrainian military officials assume that Russia may use additional weapons. Experts believe that such a threat may persist for several days to come. 

The reports come as Washington recently approved Ukraine's use of long-range Storm Shadow and ATACMS missiles to strike Russian territory, a move Western analysts say signals the US and UK's willingness to step up support for Kyiv. 

Experts suggest that information about the possible launch of the RS-26 could be part of an information war. However, the very possibility of using such a weapon is of concern to Kyiv, since the missile was originally designed to deliver nuclear charges and has a significant range.
