"Hans-Jacob Schindler, senior director at the Counter Extremism Project (CEP), said ammonium nitrate – which is also used as a fertilizer - is the “'explosive of choice' for making quick and cheap improvised explosive devices.

Overall, Schindler believes there are around 10,000 people in Germany who 'broadly agree with what Hamas does and are willing to take part in demonstrations, raise funds and share propaganda.'

Asked if Hamas’ presence would expand in the wake of the October 7 attacks, Schindler said: 'Yes, it has grown already.'"
