Officials in the United Kingdom have placed Heathrow Airport on high alert following fears of a breast implant bomb. Experts worry that female al-Qaeda members could use explosive-packed breast implants as part of a suicide bomb attack that could escape detection by airport security technology.

"There are genuine fears over this," notes one staff worker at the London-based airport. "We have been told to pay particular attention to females who may have concealed hidden explosives in their breasts."

Most breast implants are filled with silicone or another inert material such as saline. However, if this material is replaced with a liquid explosive, a female suicide bomber could potentially take down an entire aircraft.

This isn't the first time that breast implants have been found with dangerous materials. Earlier this month, a woman arriving at a Spanish airport was found to have cocaine concealed inside her breast implants. Officials only discovered the modified breast implants after the woman started bleeding.

Al-Qaeda bomb-maker Ibrahim al-Asiri ii rumored of have developed a method of hiding explosives in such implants or in body cavities. As a former chemistry student, the bombmaker has developed explosives that can pass through traditional airport security procedures, according to officials. The bombs could be detonated via chemical reaction or radio controlled devices.

The terrorist is believed to be behind the failed assassination of a counter-terrorism official in Saudi Arabia four years ago. In addition, al-Asiri is believed to be responsible for a failed attack on a plane heading for Detroit in 2009.
