German Chancellor says believes she acted responsibly after attacks

Chancellor Angela Merkel said on Thursday she believed she had acted correctly after a spate of attacks in Germany, responding to questions about why she had not visited the attack sites by saying she would attend a memorial ceremony on Sunday in Munich.

"That's a question that I obviously ask myself whenever something happens. I will be at the memorial ceremony in Munich on Sunday - I decided last Saturday to go to that memorial ceremony," she told a news conference in Berlin for which she interrupted her vacation.

"The interior minister was in Munich the day after the shooting spree (there). A decision has to be taken on this each time and perhaps some members of the public have a different view to the way I decided to do things," she added.
