Ukrainian President Volodymyr Zelensky said Tuesday that the United States has restored intelligence sharing on incoming Russian ballistic missile strikes following a brief pause of several days.

Zelensky made the announcement after meeting with U.S. envoy Steve Witkoff in Oslo, Norway. The sharing of early-warning intelligence is vital for protecting civilians, he noted, because only the United States possesses the unique capabilities to detect and report Russian ballistic missile launches in time.

"Now it works," Zelensky stated. "We are thankful to the American side."

The restoration came after a temporary interruption that left Ukraine without advance notice of some Russian strikes. Ukrainian officials had reported missing warnings for ballistic missile attacks over a three-day period amid disputes with Washington over Ukrainian strikes on Russian energy infrastructure.

The pause occurred as the Trump administration pressed for an energy ceasefire and broader peace negotiations. Witkoff is scheduled to travel to Russia on Wednesday to present proposals for three-way talks involving the United States, Ukraine, and Russia.

This latest development follows an earlier rebound in intelligence cooperation earlier in 2026 after a longer suspension in 2025. Bipartisan U.S. senators have previously credited restored data flows with improving Ukraine's defensive and strike capabilities.

Zelensky also spoke positively with U.S. Secretary of State Marco Rubio about next steps on security cooperation. The administration continues to emphasize diplomatic efforts to end the conflict while maintaining targeted support for Ukraine's defense needs.
