UK intelligence chief accuses Russia of 'staggeringly reckless' sabotage campaign

PARIS — The head of Britain's foreign intelligence service said Friday that Russia is conducting a ''staggeringly reckless'' sabotage campaign against Ukraine's Western allies, and that his spies are working to stop the consequences from spiraling out of control.

And in a message aimed in part at U.S. President-Elect Donald Trump, MI6 chief Richard Moore said that Russian victory in Ukraine would threaten American, as well as European, security.

Moore said his agency and its French counterpart were working together to a dangerous escalation by ''calibrating the risk and informing the decisions of our respective governments'' in response to President Vladimir Putin's ''mix of bluster and aggression.''

''We have recently uncovered a staggeringly reckless campaign of Russian sabotage in Europe, even as Putin and his acolytes resort to nuclear saber-rattling, to sow fear about the consequences of aiding Ukraine,'' Moore said during a speech to diplomats and intelligence officials in France.

''Such activity and rhetoric is dangerous and beyond irresponsible,'' he said.

Moore spoke alongside Nicolas Lerner, head of France's external intelligence agency, the DGSE at an event marking 120 years of the Entente Cordiale, a pact between Britain and France that bound the age-old rivals together as military and diplomatic allies.

Western security officials suspect that Russian intelligence is trying to destabilize Ukraine's allies through disinformation, sabotage and arson.

Lerner agreed that ''the collective security of the whole of Europe is at stake'' in Ukraine. He said Britain's experience tackling Russia in the wake of recent attacks like the 2018 Salisbury Novichok poisoning of a former Russian spy, was invaluable to French intelligence seeking to defuse Russian actions.

Britain and France have been among Ukrainian allies most willing to allow Kyiv to use weapons they supply – especially missiles known as Scalp in France and Storm Shadow in Britain – to hit targets inside Russia. The Biden administration recently eased its long-held opposition to U.S.-made missiles being used to strike Russia. Ukraine said last week it had used the American ATACM missiles to target Russia for the first time in the war.

Since then, Putin has lowered the official threshold for Russia's use of its nuclear weapons, and Russia has pounded Ukraine's energy infrastructure with hundreds of missiles and drones, in what Putin said was a response to the firing of the American missiles against Russian soil. Russia also fired a new intermediate-range ballistic missile, called Oreshnik, and Putin threatened to use it against ''decision-making centers'' in Kyiv, the Ukrainian capital.

In a warning to allies wavering in support for Ukraine, Moore said that ''the cost of supporting Ukraine is well-known, but the cost of not doing so would be infinitely higher.''

Trump has criticized the billions the Biden administration has spent in supporting Ukraine and has said he could end the war in 24 hours — comments that appear to suggest he would press Ukraine to surrender territory that Russia now occupies.

He said that if Russia wins, Iran and China — which so far support Moscow as ''a transaction" — would draw closer to Russia.

''If Putin succeeds, China would weigh the implications, North Korea would be emboldened and Iran would become yet more dangerous,'' Moore said.

Some European officials worry about what Trump's ''America first'' agenda means for trans-Atlantic relations, but Moore — whose name has been mentioned as a possible choice for U.K. ambassador to Washington — said he was confident the bond was strong.
