(FBIS) The following text was translated from the Madrid El Pais (Internet Version-WWW) in Spanish on 24 September 2004:
Rab’i Uthman al-Sayyid alias Mohammed El Egipcio [Mohammed the Egyptian] had on his computer photographs of explosive devices which were set off in exactly the same way as the rucksack bombs used in the 11 March attacks in Madrid, supporting the hypothesis that he was the ideologue and strategist of the Madrid attacks.
The Italian authorities have found that the briefcase bomb which appears in a photograph on El Egipcio’s personal computer used a mobile phone as a timer and was connected in the same way as the rucksack bomb defused in Vallecas police station.
The Italian authorities have handed the evidence seized from El Egipcio’s personal computer to the Spanish courts and they have been incorporated into the case being investigated by judge Juan del Olmo. The photograph shows two types of explosive devices. First, a worn dark red executive briefcase, with a particular arrangement of explosives inside. On one side the explosives are introduced under pressure in metallic cylinders, probably aluminium, to which have been screwed three large nuts, both at each end and in the middle.
The aim, according to the explosives experts, is to prevent it from moving inside the case and acting as the first shrapnel, causing greater destructive power. The suitcase contains eight cylinders which each contain 200g of explosives and are placed in two groups of three, vertically, while the other two are placed lying down on top of the other pipes. The eight cyinders are connected to mobile phone made by Trium which acts as a timer, just as in the one found in the rucksack bombs used on the death rains on 11 March, as could be seen after the defusing of the bomb found on one of the wagons of the train in El Pozo station.
The mechanism is simple, as the terrorists just set the telephone alarm. When it goes off, the current which the alarm generates causes the detonator to be activated and this detonates in the explosive in which it is placed.
