Magdeburg attack: Germany in mourning with 'no answers' to cause of Christmas markets tragedy
Magdeburg is a city of about 240,000 people, west of Berlin, that serves as Saxony-Anhalt's capital. Friday's attack came eight years after an Islamic extremist drove a truck into crowded Christmas market in Berlin, killing 13 people and injuring many others. The attacker was killed days later in a shootout in Italy.
