Germany summons Russian ambassador over Russian threats to Germany tied to drone supplier list
Berlin summons Moscow envoy after vague warnings to locations in Germany; officials say the moves aim to weaken support for Ukraine and raise security concerns.
Berlin on Monday summoned the Russian ambassador to protest what the Federal Foreign Office described as undefined and direct Russian threats to locations in Germany, saying the warnings appeared designed to undermine Germany’s support for Ukraine. The foreign ministry said Berlin will not be intimidated and called the suggested targeting of companies producing drones and components unacceptable. The move follows a Russian defence ministry publication that listed firms it said were linked to Ukrainian defence production including several German companies.
Diplomatic protest and summons
Berlin made the decision to summon the Russian envoy on April 20 2026 and delivered a formal condemnation through its Foreign Office, according to the ministry statement. Officials framed the action as a necessary diplomatic response to protect German residents and businesses and to defend the country s commitment to Ukraine. The ministry reiterated that all forms of espionage and threats on German soil are unacceptable and would be met with appropriate measures.
Nature of the alleged threats
The threats cited by Berlin were not detailed in public statements and were described as vague by German authorities. Moscow s published material listed 21 companies it identified as subsidiaries or suppliers linked to Ukrainian defence work and included wording that pointed to those locations. German officials said the language suggested those sites could be targeted and that the ambiguity of the claims did not lessen their seriousness.
Russian defence ministry publication
Last week the Russian defence ministry issued the list naming companies it said were involved in producing unmanned aerial vehicles and components for Ukraine, and it called on the European public to be informed of the locations of such enterprises. At least three German firms were named among suppliers of drones or parts in the publication, raising alarm in Berlin about the potential security implications. The Russian embassy did not provide a comment when contacted, and Moscow has not publicly amplified further operational details.
Germany Ukraine defence partnership context
The diplomatic row arrives as Germany and Ukraine deepen a strategic defence partnership that specifically includes cooperation on drone production and enhanced air defence capabilities. In a joint declaration Kyiv and Berlin pledged to strengthen cooperation on air defence and to support Ukraine s drone industry through co production ventures and other means. German officials say that closer industrial cooperation with Ukraine makes protecting dual use facilities and supply chains a growing priority.
Arrest of a German national in Russia
Russian authorities also announced the arrest of a German woman accused of involvement in an alleged plot to blow up a services facility and said she was detained with an explosive device. The arrest took place in the southern Russian city of Pyatigorsk according to statements from Russian security services, and German officials said they were aware of reports but declined further comment citing privacy and consular matters. The case has heightened bilateral tensions and prompted German officials to urge clarity from Russian authorities on the evidence and legal basis for detention.
Domestic security and industry response
German security services are reportedly reviewing the names on the Russian list and assessing any credible threat to businesses or personnel inside Germany, officials said in public comments and background briefings. Companies named have not uniformly acknowledged the claims and some German industry representatives have called for greater clarity and reassurance from both governments. Berlin is balancing the need to protect private sector operations with preserving cooperation with Ukraine on defence production.
The German foreign ministry s blunt public line that Berlin will not be intimidated reflects a broader Western concern that public naming of companies and vague references to their locations could be used to deter or disrupt support for Ukraine. Security analysts say that even ambiguous messaging can have chilling effects on supply chains and investment and that transparent, coordinated responses are key to preventing escalation.
