German police are probing a possible Islamist link to three explosions that rocked the Borussia Dortmund football team bus, after a letter found at the scene referred to the Berlin Christmas market attack, national media reported today.
The letter also mentioned Germany's deployment of Tornado reconnaissance missions as part of an international coalition battling the so-called Islamic State group, according to the daily Sueddeutsche Zeitung, regional broadcasters NDR and WDR and national news agency DPA, which did not name their sources following the Tuesday incident.
IS claimed the Berlin attack in December which killed 12 people.
