A very small amount of the novichok nerve agent was used in the attack and the highest concentration was found at Skripal’s house, it emerged in a press briefing in the city. Last week previously classified intelligence about the Salisbury attack claimed Russia had tested whether door handles could be used to deliver nerve agents. Treatment for novichok exposure would be the same as for other nerve agents, namely with atropine, diazepam and potentially drugs called oximes. According to Mirzayanov, they are 10 to 100 times more toxic than the conventional nerve agents. In the coming days residents can expect to see cordons around the most public sites replaced with secure fencing, backed by police patrols and security guards.
