Several shots were fired early today at a home for asylum seekers in western Germany and one resident was lightly injured, police said.The shots were fired at a window of the building in the town of Dreieich at around 2.30 a.m (0130 GMT), and one hit a 23-year-old asylum seeker who was sleeping, according to police in Offenbach, near Frankfurt. He was taken to a hospital, but was able to leave shortly afterward.It wasn't immediately clear who was responsible for the incident or what the motive was. However, Darmstadt prosecutors' spokeswoman Nina Reininger told news agency dpa: "If someone shoots at housing which has people inside, I assume that it is a targeted attack."Police didn't specify the nationality of the injured migrant. Local authorities said 30 people were living in the building and that 15 men - 14 Syrians and an Afghan - were in the part that was fired at.Germany saw around a million asylum seekers arrive last year. While Germans have generally been welcoming, there have been arson attacks, assaults and other crimes against refugee shelters.
