The jury in the trial of three men from Birmingham accused of plotting a suicide bombing campaign in the UK has been told that the defendants discussed how to make explosives and how many people they could kill.
Irfan Naseer, Irfan Khalid and Ashik Ali deny between them 12 terrorism charges, and are on trial at Woolwich Crown Court.
Outlining the prosecution’s case against the men for a fourth day, Brian Altman QC read transcripts of conversations recorded by counter terrorism police during a surveillance operation last year.
The jury was told that the three men had spoken about the use of fertiliser and the use of prills found in sports injury cold packs, which are sometimes manufactured from ammonium nitrate. The court heard that the men had discussed using ammonium nitrate to make a home made explosive. The transcript continues with detailed discussions of methods and formulas for making a bomb.
The court was also played a recording of a conversation between Irfan Naseer and Ashik Ali. Naseer is allegedly heard saying:
“what you do is innit, you know this here your empty syringes in there yeah, if you make this before like two days before you explode it …so now, soon as the current goes from this one it’s gonna go boom innit.”
The jury was told police later found a diagram containing what was described as a blueprint for a viable home made explosive.
In a later conversation played in court Irfan Naseer is allegedly heard discussing how many people might be killed by the explosives, especially if shrapnel like nuts or nails were sellotaped to it. They are also heard discussing how the bombs would be carried:
“you probably kill about 25 people with 1KG one. But the noise will take people, you probably kill about 20, probably injure about 60, 50…. “
“1kg is like the noise of about 50 bullets together.”
“7 or 8 of them in different places with timers on so all for like the same time probably to go boom boom boom everywhere.”
