Russia warns of nuclear retaliation after Ukraine launches missiles into its territory

Russia has warned of potential nuclear retaliation after Ukraine launched U.S.-made ATACMS missiles into Russian territory. Russian officials described the attack as an escalation, with President Putin signing amendments to allow nuclear strikes in response to conventional attacks. In response to the missile strikes, Russia is mass-producing mobile bomb shelters for protection against nuclear threats. The shelters can accommodate 54 people and are designed to be easily transportable. Concerns are growing in Europe about its preparedness for Russia's hybrid warfare tactics. Reports indicate that Russia is redeploying military assets in anticipation of further Ukrainian strikes, while the U.S. has approved the use of ATACMS missiles by Ukraine.
