UK Security Minister Ben Wallace said Saturday that Britain would respond to the Salisbury attack with the "full force of the United Kingdom's resources if that is an appropriate and proportionate thing to do."
Speaking to BBC Radio 4, Wallace described the attack as a "very serious incident with horrendous outcomes." However, he cautioned against rushing to judgment on who is responsible.
"We want to make sure we are effective in whatever our response is. If that is arresting a couple of people and getting them in jail, then that is what we shall do. If it's further, there are lots of things that the United Kingdom can do -- it is a powerful country, with a powerful economy, powerful allies, powerful military and powerful other capabilities. And we shall look at those -- all."
