Terrorists of Al-Qaeda on the Arabian Peninsula claim they have invented a bomb that can pass through a metal detector.
According to their own electronic edition Inspire, such bombs can be made of simple materials that are readily available even in the USA. In the first twenty pages the author explains how to make such explosives in one's own kitchen.
American security experts say that such statements should be treated with all seriousness, as terrorists have been working on "unrecognizable" bombs for a really long time. However, security forces continue to develop new methods to detect explosives.
