"I can guarantee that Russian Federation has not tampered with the site", Lavrov told the BBC on Monday.
The U.S., United Kingdom and France launched strikes on Syria a week after U.S. President Donald Trump said there would be a "big price" to pay for the apparent use of chemical weapons by President Bashar al-Assad's forces in the town of Douma, an attack that killed scores of civilians.
An "electronic attack" was one of a handful of reasons given for why Syria's air defence system kicked into action last night, as the country's state media stepped back from initial reports that it had been hit by another round of missile strikes.
German President Frank-Walter Steinmeier warned against demonising Russia and said the air strikes raised the risk of a direct confrontation between USA and Russian forces in Syria for the first time.
The suspected chemical attack is the latest issue to heighten tensions between Russian Federation and Western powers.
Mrs May spoke in Downing Street in the hours after the blitz and insisted the action was a limited and targeted strike to degrade and deter the Syrian government.
A team of independent investigators have been prevented from reaching the scene of an alleged chemical attack by Syrian and Russian officials. In a statement, she said: "The U.S. mission has not changed - the President has been clear that he wants U.S. forces to come home as quickly as possible".More news: Police arrest 12 'Offa robbers', recover phones, iPads

A significant body of information, including intelligence, indicates the Syrian Regime is responsible for this latest attack.
The timing chosen for this escalation, on the eve of important Arab events, and the absence of the usual appropriate consultations, may raise questions, misunderstanding and indignation, the source said.
A false alarm led to Syrian air defense missiles being fired overnight and no new attack on Syria took place, Syrian state media and a military commander said on Tuesday.
Foreign Minister Boris Johnson defended the strikes, saying Britain had a duty to show Syria had not "got away" with using chemical weapons.
They say after all the violence that's been going on in their country for the past seven years they were happy about the attacks at first, thinking it was the rest of the world finally gaining a conscious for the horrors that have been a sad reality in their country.
The U.S. and France say they have evidence that poison gas was used in the April 7 attack in the opposition-held town of Douma, killing dozens of people, and that Syrian President Bashar Assad's military was behind it.
Despite a US-Russian agreement to completely eliminate Syria's chemical weapons program after hundreds of people were gassed with sarin in Ghouta on 21 August, 2013, the OPCW had been unable to verify that all manufacturing, storage and research facilities were destroyed.
Nikki Haley, the U.S. ambassador to the United Nations, said treasury secretary Steven Mnuchin will announce on Monday further economic sanctions on Russian Federation for supporting the Syrian regime. It's unclear if the strikes were effective.
He said, "Ten days ago, President Trump wanted to withdraw from Syria".
