Police said a man who bombed a London subway train bought most of the bomb parts online. Police accused an 18-year-old Iraqi refugee of bombing a busy commuter train. The bomber left the bomb on a packed train during the rush hour. It exploded at Parsons Green station at 8.20am. About 30 passengers had burns to their face and body. Police said there would be more people hurt if the bomb had worked properly. It didn't detonate fully. Police said the bomb contained, "knives, screws, glass and similar items to increase the likelihood of death".
The bomber bought many of the ingredients for his bomb from Amazon. One ingredient was several hundred grams of an explosive called TATP. It is called "Mother of Satan" because it is so powerful. Police said the bomber wanted to create "maximum destruction". Reporters checked Amazon and were shocked to find that the site directed visitors to other things that could be used to make bombs. Amazon said it will stop this happening, saying: "In light of recent events, we are reviewing our website to ensure that all these products are presented in an appropriate [way]."
