Evidence

A search found one direct source, Ukrainska Pravda's English-language edition (pravda.com.ua), reporting that Colonel Andrii Demchenko, spokesperson for Ukraine's State Border Guard Service, stated that repeaters located in Belarus have been boosting the signal for Russian drones targeting western Ukrainian oblasts since late last week. The wording in the article matches the claim almost verbatim, indicating the claim is an accurate paraphrase of an official Ukrainian government statement. However, repeated search attempts to find independent corroboration (other outlets, Reuters, AFP Fact Check, Bellingcat, or EUvsDisinfo coverage) were not possible due to search tool limits being reached during this session, and no existing fact-check verdict on this specific claim was located before the limit was hit. The underlying technical assertion (that repeaters in Belarus are boosting Russian drone signals) is a battlefield intelligence claim from a Ukrainian military/security source that has not been independently verified through open-source or forensic analysis by a recognized fact-checking body.
