(London Daily Mail) Heathrow Airport is on high terror alert amid fears female terrorists might use breast implants as bombs, it emerged today.

Experts believe there is a ‘credible’ threat that al-Qaida could target flights out of London using explosives hidden in the chests of its operatives.

Specialists believe women could have had breast surgery with implants which, if injected with another liquid, will cause a large enough explosion to take down a plane.

Sources have said that security at Heathrow is taking longer as they check busts.
