The US deployed more than 300 bio-laboratories around the world, many of them located in former Soviet republics, Russian Foreign Minister Sergey Lavrov said in an interview with the RT TV channel.

According to him, Ukraine is probably the biggest project from the Pentagon's point of view, which disposes of the activities of these laboratories. "We need a mechanism that would allow us to respond, that would allow us to achieve transparency in this military-biological activity anywhere, on our own territory or abroad," he said.

Lavrov said Moscow will insist that the issue be taken up within the BWC as well as within the UN Security Council because it poses a clear threat to international peace and security.
