BERLIN (Reuters) - A patient shot a doctor in a university clinic in Berlin on Tuesday before killing himself, but there were "no signs at all" of a link with Islamist militancy, police in the German capital said.

Germany is on edge because of a spate of violent attacks on civilians by men of Middle Eastern or Asian origin since July 18 that have killed 10 people. Islamic State militants claimed responsibility for two of those four attacks before Tuesday.
