U.K. police have said a man who put a bomb a London subway train bought most the parts the bomb online. Police have accused an 18-year-old Iraqi refugee planting the bomb a busy commuter train on September 15. The bomber left his device a packed subway carriage the peak rush hour. The bomb exploded Parsons Green subway station at 8.20am. It caused burns to the face and body 30 passengers. Police said there would have been more casualties if the bomb had worked properly. It didn't detonate fully so there was less harm to humans than there could have been. Police said the bomb contained, "knives, screws, glass and similar items to increase the likelihood death."

The bomber bought many the ingredients his device the online shopping site Amazon. One these ingredients was several hundred grams an explosive called TATP. This is also called "Mother of Satan" because it is so powerful. Police said the bomber used it to create "maximum destruction". Reporters later checked Amazon the ingredients and were shocked to find that the site directed them to other things that could be used to make bombs, the "items frequently bought together" tab. Amazon said it will work to stop this happening. It said: "In light recent events, we are reviewing website to ensure that all these products are presented an appropriate [way]."
