Porton Down scientists unable to establish where the nerve agent that poisoned the Skripal's was made

The video discusses the investigation into the poisoning of Yulia and Sergei Skripal, identifying the nerve agent as Novichok. While the source remains unverified, the UK government holds Russia responsible, supported by multiple intelligence sources. The Russian Embassy challenges this, but Porton Down maintains high security standards. The international community largely supports the UK's stance. The Skripals remain hospitalized, with Yulia's condition improving, as the investigation continues.
