Metropolitan Police Assistant Commissioner Neil Basu said that the investigators from the UK's counter-terrorism network are unable to say if the nerve agent found in the Amesbury incident related to the attack on former Russian spy Sergei Skripal and his daughter Yulia, in London on Monday.

The couple were taken to Salisbury hospital after being found unconscious and in a critical condition at an address on Muggleton Road in Amesbury last Saturday. Police have since declared it a 'major incident' and cordoned off a number of locations in the Amesbury and Salisbury area. UK counter-terrorism officers have also joined the investigation. Amesbury is a short distance from the UK chemical weapons laboratory Porton Down and the site where Sergei and Yulia Skripal collapsed after being allegedly poisoned by a nerve agent in March.
