Estonia says Russia behind arson attack, NATO offers support

Estonia said on Tuesday it blamed Russian operatives for an arson attack, prompting NATO allies to offer security and investigative assistance.

NATO offers security support

Officials said the allegation was made in a government statement issued on Sept. 29, 2026; the claim that Russia was behind the attack was attributed to Estonian authorities. Allies offered to assist with forensics and intelligence-sharing, officials said, and pledged to monitor the situation closely.

Estonian officials described the incident as part of a broader pattern of hostile acts, though they stopped short of laying out public evidence in full, officials said. NATO partners said they would coordinate support while investigations continue, officials said.

Officials said Tallinn will brief NATO partners on Sept. 30, 2026, when allies will consider any additional collective measures. The coming 24–48 hours are likely to show whether the episode leads to tighter allied security cooperation or remains a bilateral crisis, officials added.
