British intelligence have reportedly foiled a plot by Islamic extremists to assassinate Prime Minister Theresa May.

The disrupted plot against May included an explosive device that terrorists planned to detonate in front of May’s residence on Downing Street, according to Sky News.

“It is in essence an extreme Islamist suicide plot against Downing Street,” Sky correspondent Martin Brunt said.

“Essentially police believe that the plan was to launch some sort of improvised explosive device at Downing Street and in the ensuing chaos attack and kill Theresa May, the Prime Minister.”

The plot was just one in a number of planned attacks this year that cops and British security services have been able to prevent, Sky said.

It was not clear Tuesday night what stage the plot was in or if any suspects have been arrested.
