The Russian military made an astounding charge Friday that a chemical attack on civilians in Syria was staged and directed by Britain.

“We have … evidence that proves Britain was directly involved in organizing this provocation,” Russian Defense Ministry spokesman Igor Konashenkov said during a televised briefing, according to Reuters.

Konashenkov claimed Britain had told the White Helmets, who serve as first responders in rebel-held areas, to fake the attack in the town of Douma in Eastern Ghouta.

London put “powerful pressure” on the civil defense organization, he said, Agence France-Presse reported.

Konashenkov said the suspected poison attack was staged April 7 to coincide with military action by Syrian government troops after the rebel group Jaish al-Islam shelled the capital, Damascus, from April 3 to 6.

Volunteer aid workers and activists claimed the attack by the Syrian government killed more than 40 people — sparking an international outcry and prompting Washington and its allies to consider a military response.

Moscow warned against any strikes and threatened to retaliate.

The Russian accusation comes as London has blamed Moscow for a nerve agent attack on former double agent Sergei Skripal and his daughter, Yulia, in the English city of Salisbury last month.

In March, Russia’s General Staff said rebels were planning a “provocation” in Eastern Ghouta with women and children set to play victims of a chemical attack.

Russian strongman Vladimir Putin claimed on April 4 that the Kremlin had “irrefutable proof” that rebels were planning an attack with “poisonous substances.”

On Friday, Konashenkov released statements by medics from Douma’s hospital who said several people carrying video cameras entered the hospital, shouting that its patients were struck with chemical weapons and causing panic.

The medics said none of the patients were hurt by chemicals.

Russian Foreign Minister Sergei Lavrov claimed earlier Friday, without offering any evidence, that the suspected attack in Douma was staged with the help of an unspecified foreign intelligence agency.

Other Russian officials — both from Moscow and speaking at the UN — alleged after the attack that the images of the victims were a sham.

Speaking to reporters in Moscow, Lavrov doubled down on a strong warning to the West against military action in Syria, saying any such action there would increase flows of refugees into Europe.

“I hope no one would dare to launch such an adventure now,” Lavrov said.

Russia has been a staunch ally of Syrian President Bashar al-Assad’s regime and has helped turn the tide of war in his favor since entering the conflict in September 2015.

A fact-finding mission from the Organization for the Prohibition of Chemical Weapons is expected to head to Douma — and both the Russian military and the Syrian government said they would facilitate the mission and ensure the inspectors’ security.

On Wednesday, President Trump taunted Russia for backing a “Gas Killing Animal” — referring to Assad — and defied a threat from Moscow that it would shoot down US missiles.

“Get ready Russia, because they will be coming, nice and new and ‘smart!’” Trump wrote on Twitter.

Less than an hour later, he softened his stance and wrote: “Our relationship with Russia is worse now than it has ever been, and that includes the Cold War. There is no reason for this.”

And after being criticized for telegraphing an expected retaliatory military strike, Trump tweeted that he “never said when an attack on Syria would take place. Could be very soon or not so soon at all!”
