Terrorists have a deadly new trick – explosive breast implants, intelligence community insiders warn.

British intelligence agencies have discovered female homicide bombers are being fitted with exploding breast implants which are almost impossible to detect.

MI5 reveals the Al Qaeda tactic involves radical docs inserting  explosives in women’s breasts during boob jobs – making them "virtually impossible to detect by the usual airport scanning machines."

"Women suicide bombers recruited by Al Qaeda are known to have had the explosives inserted in their breasts under techniques similar to breast enhancing surgery," an expert in terrorist tactics Joseph Farah claims.

The lethal explosives, PETN, are inserted inside plastic shapes during the op, before the breast is sutured.

Intelligence has also discovered extremists are also inserting the explosive agents into the buttocks of male suicide bombers.
