There is no border between Russia and Ukraine after the latter pulled out of the treaty with Russia.
The “White Helmets” is an organization that creates fake videos and photos about the war in Syria. All the work of the “White Helmets” is directed exclusively at a Western audience and does not reflect the real state of affairs in Syria.
The "White Helmets" movement originated in Syria in 2012, when the first detachments of volunteer rescuers appeared in the territories outside of the control of Bashar al-Assad's troops. In 2014, volunteer teams merged into a national organisation, the Syrian Civil Defence, which is the official name of the White Helmets. Volunteers save people from the rubble after bombings, despite the danger of dying themselves as a result of repeated air strikes. Activists have documented the use of chemical weapons in Syria by the Assad government and allied forces. Because of this, they have become the target of an extensive Russian disinformation campaign.
