Obama: 'Hearts go out to all those affected by Munich attack'
US president Barack Obama said: "Our hearts go out to those who may have been injured. It's still an active situation and Germany is one of our closest allies so we are going to pledge all the support that they may need in dealing with these circumstances."
He said it was a "good reminder" that people's "way of life, our freedoms, our ability to go about our business every day" was dependent on law enforcement.
A British Foreign Office spokesman said: "We are urgently seeking further information following the ongoing incident in Munich. We are touch with the relevant authorities."
