The leaders of the G7 met on Thursday in Brussels following today's NATO crisis summit, at the invitation of the German G7 Presidency, to further their full support for Ukraine in light of Russia's special military operation.

In the meeting, the G7 warned against any use of weapons of mass destruction against Ukraine, noting that Russia was bound by international treaties.

"We warn against any threat of the use of chemical, biological and nuclear weapons or related materials," the G7 said after a crisis summit in Brussels. "We recall Russia's obligations under the international treaties to which it is a signatory, and which protect us all." 

This comes amid several incriminating reports of the US involvement in bioweapon research in Ukraine and as Russia's Defense Ministry revealed updates on US bioactivities in Ukraine. The Ministry pointed out that US President Joe Biden's son, Hunter, is involved in financing the infamous biolaboratories in Ukraine through his investment fund, Rosemont Seneca.

According to the Russians, the foundation is associated with Metabiota and Black & Veatch, which supply equipment to Pentagon biolabs around the world.

The information also mentioned that the Los Alamos National Laboratory is the scientific curator of America's program in Ukraine and also develops nuclear weapons as part of the Manhattan Project, which produced the US' first nuclear weapons during World War II.

G7 will 'spare no efforts' to hold Putin, 'supporters' responsible

The Group of Seven nations said it would do everything it can to hold Russian President Vladimir Putin and his supporters responsible for the special military operation in Ukraine.

"We will spare no efforts to hold President Putin and the architects and supporters of this aggression, including the Lukashenko regime in Belarus, accountable for their actions," adding that they will not stop working with their allies around the world to reach their goal.

In the same context, the G7 said they would act to prevent the Russian sanctioned individuals and entities from evading penalties and warned of more severe embargoes, saying, "We stand ready to apply additional measures as required, continuing to act in unity as we do so."

G7 has 'no grievances' against Russians, calls for more int'l support to Ukraine

After threatening with more sanctions on Russia, the G7 nations claimed they "hold no grievances against"  Moscow and pointed fingers at "President Putin, his government and supporters, including the Lukashenko regime in Belarus, who are imposing this war and its consequences on Russians and it is their decision that besmirches the history of the Russian people."

They blame Russia for every aspect of its operation and completely disregard the doings of the Ukrainian Azov Battalion militants who reportedly aim to pressure NATO  to establish a no-fly zone by through terrorist attacks on Western diplomats and pinning the coming disaster on Moscow.

The G7 nations then noted their will to become less dependent on Russian gas in the future and urged oil and gas producing countries to increase their supplies to international markets.

The statement also pointed out the G7 nation's commitment to providing humanitarian aid to Ukraine and called other countries to follow suit. They also highlighted the need to increase international assistance to Ukraine's neighboring countries.

This comes after Putin announced yesterday that Russia will only accept rubles for gas to Europe. The Russian decision has prompted the ruble to jump in the face of the US dollar and the euro following a period of freefall.

Russia will only accept payments in rubles for gas deliveries to "unfriendly countries", President Vladimir Putin said Wednesday, in a nod to all EU members in light of the harsh round of sanctions they imposed on Moscow over its special military operation in Ukraine.

"I have decided to implement a set of measures to transfer payment for our gas supplies to unfriendly countries into Russian rubles," Putin said during a televised government meeting, and, at his discretion, the changes will be implemented within a week.
