U.S. Urges Russia to Refrain from 'Systematic Strikes' on Kyiv; Moscow Dismisses Appeal and Reiterates Evacuation Warning

U.N. session hears sharp U.S. criticism after weekend barrage that included an Oreshnik intermediate-range ballistic missile strike

By Avery Klein

The United States strongly urged Russia not to carry out its threatened 'systematic strikes' on Kyiv after a weekend bombardment of the Ukrainian capital and surrounding areas. Russia rejected the U.S. appeal, defended the attacks as aimed at military and intelligence targets and warned foreign diplomatic staff to depart Kyiv. The U.N. expressed deep concern over the prospect of continued assaults on the city.

U.S. Urges Russia to Refrain from 'Systematic Strikes' on Kyiv; Moscow Dismisses Appeal and Reiterates Evacuation Warning

Key Points

  • U.S. publicly urged Russia not to mount "systematic strikes" against Kyiv during a U.N. Security Council session, criticizing the use of an Oreshnik intermediate-range ballistic missile as "an inexplicable, dangerous and barbaric escalation" - impacts diplomacy and geopolitical risk assessment.
  • Moscow rejected the appeal, said the strikes targeted Ukrainian military and intelligence facilities, and reiterated warnings for foreign diplomats and international staff in Kyiv to leave - affecting diplomatic operations and international organizations.
  • The Sunday barrage killed at least two civilians and injured about 100 people; Russia said it was retaliating for a Ukrainian strike on a student dorm in Donetsk, while the U.N. expressed deep concern over Russia’s stated intention to pursue "consistent and systemic strikes" - implications for civilian safety and humanitarian response.

The United States on Thursday issued unusually stern criticism of Russia and called on Moscow to refrain from launching its pledged "systematic strikes" against Kyiv, but the Russian government dismissed the appeal and renewed its warning for foreign diplomats to leave the Ukrainian capital.

The comments were made during a United Nations Security Council session that Ukraine had requested in response to a barrage on Sunday that used hundreds of drones and missiles against Kyiv and nearby areas. Among the weapons Russia used in the assault was an Oreshnik intermediate-range ballistic missile, a nuclear-capable system that, according to public accounts cited in the session, has been fired into Ukraine at least three times since November 2024.

Condemning the Sunday attack, Tammy Bruce, the deputy U.S. ambassador to the U.N., characterized Russia’s use of the Oreshnik as "an inexplicable, dangerous and barbaric escalation" of the conflict that began with Russia’s full-scale invasion in February 2022. She added: "We caution Russia not to mount so-called systematic strikes against Kyiv, which risk further civilian casualties and setting back the prospect of peace."

The bombardment killed at least two civilians and injured roughly 100 people, according to reports discussed during the session. Moscow has said the operation was a response to a Ukrainian strike on a student dormitory in Donetsk, the eastern region that Moscow-backed separatists seized in 2014.

Bruce’s remarks represented some of the most forceful criticism of Russia issued by the Trump administration, whose public stance toward Moscow has been more accommodating than that of many U.S. allies. She did not specify how the United States would react if Russia were to follow through on its threat of "systemic strikes."

In response, Russian Ambassador Vassily Nebenzia repeated Moscow’s assertion that the Sunday attacks had targeted key Ukrainian military and intelligence installations and reaffirmed Russia’s intention to strike "decision-making centers and command posts." He said these facilities are "dispersed throughout Kyiv," and cited that fact in explaining Russia’s advisory to foreign citizens, including staff of diplomatic missions and offices of international organizations, to "leave the city as soon as possible."

U.N. Assistant Secretary-General Khaled Khiari told the council the United Nations was "deeply concerned" by Russia’s stated plans for "consistent and systemic strikes" on targets in Kyiv.


The Security Council session highlighted a series of immediate humanitarian and diplomatic implications from the weekend’s bombardment and the ensuing rhetoric: civilian casualties and injuries in Kyiv, public warnings to foreign diplomatic personnel to depart the capital, and renewed international alarm over the use of an intermediate-range missile system in the conflict.

Risks

  • Potential for increased civilian casualties if Russia carries out threatened "systematic" or "systemic" strikes, which could exacerbate humanitarian needs and strain emergency services (impacts: humanitarian sector, local services).
  • Evacuation advisories for diplomatic staff and international offices in Kyiv risk disrupting diplomatic activities and coordination of assistance, creating uncertainty for international organizations operating in Ukraine (impacts: diplomacy, international NGOs).
  • Uncertainty over how the United States or other states might respond to further Russian strikes, since the U.S. did not specify a response, contributes to geopolitical and market uncertainty, particularly for sectors sensitive to geopolitical risk (impacts: defense, risk-sensitive financial markets).
