Authorities evacuated Luton Airport, about 30 miles north of London, after a suspicious item was found in the security search area. Incoming flights were canceled and the airport road was closed. The item was later destroyed in a “controlled explosion.” Sir Peter Wall, the outgoing head of the Army, warned that the UK has little idea of the capabilities and strength of the Islamic State, but said the organization “will pose an even great threat if we take no action against them.”
