A 5-year-old girl and a teenager have been injured after a man opened fire on a refugee shelter in Germany with an air rifle.

A 21-year-old man has been accused of shooting at the refugee shelter from his third floor apartment  located just 40 meters away from the camp in the northwestern German town of Lingen.
