Guardian: UK on missile terror alert
Heathrow was last night being patrolled by 1,500 anti-terrorist police and troops after intelligence warnings identified it as a likely target for an imminent attack by al-Qaida-linked militants armed with anti-aircraft missiles.
The move was sanctioned late on Monday after high level meetings at Scotland Yard headed by Assistant Commissioner David Veness, who requested immediate army back-up and support from Heathrow's neighbouring forces, Surrey and Thames Valley.
