May: We should not underestimate the terrorism threat

Home Secretary Theresa May told the Conservative Party conference: "We should not for one second underestimate the threat we face from terrorism and the challenges we must meet in confronting extremism."

"Whatever the race, religion and beliefs of a terrorist, whatever the race, religion and beliefs of their victims, this is Britain.

"We are all British. We stand united against terrorism and we will never succumb to violence."
