U.S. specialists ran clinical trials of medications with serious side effects in Rubezhnoye, said Chief of Nuclear, Biological and Chemical Protection Troops of the Russian armed forces Lieutenant-General Igor Kirillov.   “The United States conduct the most questionable research from the point of view of international law outside its national territory,” Kirillov said at a press briefing which addressed the analysis of documents on U.S. military biological activities.   “The Pharmbiotest medical center in the liberated territory of the Lugansk People’s Republic was searched in the course of the special military operation,” he said. “It had run clinical trials of medications with serious side effects; these are drugs to treat leukemia, mental and neurological disorders, epilepsy and other serious diseases.”   In early 2023, local residents in Lisichansk found a large dump of biological materials belonging to Pharmbiotest, Kirillov said.   Clinical specimens and medical treatment records with patients’ personal data were buried in the ground instead of being cremated as required by regulations. “It shows that the evidence was destroyed in great haste,” the military official said.   The Ukrainian government launched the so-called anti-terrorist operation against Donbass in April 2014.  The peace talks that began soon thereafter failed to reach tangible results due to Kiev’s position to settle the conflict by force.   On February 24, 2022, Russian President Vladimir Putin announced a special military operation to protect Donbass residents from Ukrainian aggression. Prior to that, LPR and DPR Heads Leonid Pasechnik and Denis Pushilin asked the Russian leader to provide military assistance. The LPR militia and Russian armed forces fully liberated the LPR territory from Ukrainian armed formations on July 3.   The Lugansk People’s Republic acceded to Russia on September 30, 2022 following the unification referendum.*i*ie
