This report coincides with the recent seizure in Germany of hundreds of litres of hydrogen peroxide (an essential component of TATP home-made high explosives) and the arrest of a number of Germans. German police believe the bombers were planning to attack Frankfurt airport, as well as restaurants and discotheques.
Following the London tube bombings of 2005 strict controls were put in place over the supply of hydrogen peroxide. In many other countries no such controls exist, and instructions on how to convert the chemical into powerful explosives can still be accessed on the Internet!
