Dnipro, Ukraine's fourth-largest city, has served as a key logistics and humanitarian hub during the full-scale war. The city has recently been a target of intensified Russian attacks.
Russia launched its Oreshnik intermediate-range ballistic missile (IRBM) at Dnipro Nov. 21, marking the first time such a weapon has been deployed against Ukraine during the war.
Russian President Vladimir Putin claimed on Dec. 13 that Russia is preparing to attack Ukraine with another Oreshnik missile this weekend.
