Germany is in shock after a school shooting which has left 16 people dead. A 17-year-old opened fire at his former school in a town near Stuttgart.Nine students, aged between 14 and 16, and three teachers died at the school, as well as one person at a nearby clinic. After fleeing with a hostage in a car, the gunman was killed in a shootout with police. Two passers-by died in the shootout and two policemen were seriously wounded. The former student, described as someone who kept to himself, was dressed in black combat gear when he entered the school. This is the third school shooting in Germany in seven years. In 2006 a man opened fire in a college in the western town of Emsdetten, wounding at least 11 people before committing suicide. In April 2002 Germany suffered its worst school shooting when a gunman killed 17 people, including himself, at a high school in the city of Erfurt.
