Attacks by Islamist militants pose the biggest security threat for Germany and events like the shooting and bombing in Istanbul this week could happen in Germany, the head of the country's domestic intelligence agency (BfV) told a Saturday newspaper.
Three suspected Islamic State suicide bombers killed 44 people at Istanbul's main airport on Tuesday, the deadliest in a string of attacks in Turkey this year.
