The British warship [which sailed on the Black Sea near Russia-occupied territorites] committed a provocation. This was a conscious and planned action.
US biolaboratories in post-Soviet countries [can] be the basic structures for the spread of pathogens dangerous to humans in adjacent territories. The United States has tightly surrounded the borders of Russia with its biological laboratories, but most of them are in the post-Ukrainian space, of them only 15 are widely known. Former Ukraine has the central role in the US plans to conduct bacteriological warfare against Russia.
Since the post-Ukrainian space is under complete US control, the United States can turn it into a hotbed of deadly diseases on the border with Russia.
Recurring unfounded claims alleging that the United States develops biological weapons and has secret biological laboratories around the world as well as Ukraine being controlled by the US. See similar cases here claiming that Ukraine is a colony, governed by a puppet regime, and here a claim about how Ukraine "sold its self to external control".
Russian media are continuously spreading disinformation about "secret military biological laboratories in Ukraine". In fact, there are no secret US laboratories in the country. A complete list of medical and scientific laboratories that the Pentagon has supported under the agreement since 2005 is on the website of the US Embassy in Ukraine, along with documents and amounts spent on the reconstruction of a particular facility.
The US Embassy in Ukraine has repeatedly denied the "creation of military biological laboratories" in Ukraine.
The cooperation between Ukraine and the United States in the direction of combating biological terrorism takes place exclusively within the framework of Ukrainian legislation and in the interests of Ukraine.
In 2005, the Ministry of Health of Ukraine and the U.S. Department of Defence signed a framework agreement on preventing the spread of technologies, pathogens, and knowledge that can be used in the development of biological weapons. Within the framework of this Agreement, a number of state laboratories located in Odesa, Kharkiv, Lviv, Kyiv, Vinnytsia, Kherson, and Dnipro regions were modernised (repair works were carried out, equipment was updated, consumables were purchased, etc.).
The Security Service of Ukraine emphasises that these laboratories are financed from the state budget, subordinated to the Ministry of Health and the State Service of Ukraine for Food Safety and Consumer Protection.
See similar disinformation cases alleging that the US is encircling Russia with biological weapons and that it invests in biolaboratories in Ukraine: the US is experimenting with people and creating biological weapons in Georgia; Washington is creating biological weapons on the borders of Russia and China; COVID-19 likely the fault of the US; it runs dozens of deadly biolabs around the world; the US is developing biological weapon in post-Soviet republics; US biolabs have been developing new biological weapons in Ukraine.
