"Germany Investigates Paris Tourist Killing as French Minister Warns of Ongoing Islamist Terrorism Threat"

German prosecutors have launched an investigation into the killing of a German tourist in Paris over the weekend. The suspect, who had pledged allegiance to ISIS, attacked a German couple near the Eiffel Tower, killing one and injuring the other. He then attempted to attack two more people with a hammer before being apprehended by the police. The investigation will run alongside a French probe, and the suspect is being investigated for membership in a terrorist organization abroad and murder. Experts suggest that this attack demonstrates the new trend of inspiring individuals online to carry out attacks, as ISIS seeks to regain relevance.
