BBC Online :The so-called Islamic State has released a video purporting to show an Afghan asylum seeker making threats before attacking a German train.The 17-year-old injured four people with an axe and knife, one critically, in the attack in Wuerzburg on Monday evening. He was shot dead by police.In the video, a young man brandishing a knife says he is an “IS soldier” preparing for a suicide mission. German officials say they later found a hand-painted IS flag in his room.The teenager reportedly shouted the Islamist slogan “Allahu akbar” (“God is great”) during the attack.The self-styled news agency of IS said he had launched the attack “in answer to the calls to target the countries of the coalition fighting the Islamic State”. The attack comes days after a lorry ploughed into a crowd in Nice in France, killing 84 people. The self-styled Islamic State group said one of its followers had carried out that attack.In the video, IS identified the attacker as Muhammad Riyad, who can be heard speaking Pashto.Joachim Herrmann, the interior minister of the state of Bavaria, said the flaghad been found among the teenager’s belongings in his room in his foster home in the nearby town of Ochsenfurt.A text written in Pashtun was also found, he said, and it showed a strong indication that the teenager “could be a person who had been self-radicalised”. Mr Herrmann said those who had interacted with the young man in recent months described him as calm and quiet and they could not understand his actions.
