The eight members of the panel who produced the report are from different countries and have expertise in many fields relating to how weapons of mass destruction are created, how they are shipped between states to circumvent detection and whether sanctions are being busted. Russia, however, has protected Assad from accountability for these actions, using its veto on the U.N. Security Council in November to scuttle a separate panel investigating the use of chemical weapons by actors on both sides of the Syrian civil war.
Syrian dictator Bashar al-Assad has allegedly been using chemical weapons on its own people since, at least, 2012 - and it appears North Korea might be helping him.
William Newcomb, who chaired the United Nations panel of experts on North Korea from 2011 to 2014, described the report "an important breakthrough".
Mr Johnson added: "If there is incontrovertible evidence of the use of chemical weapons, verified by the OPCW [Office of the Prohibition of Chemical Weapons] - if we know that it's happened and we can demonstrate it, and if there is a proposal for action where the United Kingdom could be useful, then I think we should seriously consider it".
Flames following a reported rocket attack is seen on the horizon in the rebel-held enclave of Eastern Ghouta on February 28, 2018. The intelligence source told the BBC, the Syrian government's allies, Iran and Russian Federation, are well aware of the manufacturing of chemical weapons at these facilities. There have been allegations that Syrian President Bashar al-Assad's government has been using chemical weapons in attacks, including in a sarin gas attack on Khan Sheikhoun past year.
But a confidential report, compiled by a UN Panel of Experts which assesses North Korea's compliance with UN resolutions, found evidence of illicit supplies sent to Syria.
Syria has periodically sought to appease the global community on the subject of chemical weapons.
Is North Korea Supplying Chemical Weapons To Syria? It is unclear, however, if the report will be released.
It agreed to give up its chemical weapons stock to worldwide investigators after a sarin attack in eastern Ghouta in 2013 which killed hundreds of people - widely believed to be the worst chemical incident in modern history. A statement from besieged Eastern Ghouta's interim health ministry said victims in the town of al-Shifoniyeh had been admitted to hospital with convulsions, difficulty breathing and irritation of the eyes and mouth following an air strike on Sunday night.
Since taking office more than a year ago, President Trump has met North Korean threats and bombast with fiery rhetoric in kind, but American demands for denuclearization - a US precondition for potential talks, dangled by the North as the Olympic Games wrapped up on Sunday - are widely considered likely to be futile.
