Picked up on Instapundit where the story read:

PRECAUTIONARY MEASURE “NOT RELATED TO TERRORISM” IN SIDNEY, AUSTRALIA: Sydney Opera House evacuated and Manly ferry cancelled during police operation.

So they can’t spell Sydney in America. This, however, is what they were referring to:

The Sydney Opera House precinct reopened to the public Thursday afternoon after a police operation caused staff and tourists to be evacuated from the landmark.

Police simultaneously conducted an operation across the harbour in Manly as a “precautionary measure” following information on social media.

“Following information on social media, police conducted an operation in the vicinity of the Opera House and Manly as a precautionary measure,” police said.

It is understood the operation, which began just after lunchtime and was over by mid-afternoon, was not related to terrorism.

Well, that’s a relief. One suggestion of what it was all about is found at the comments thread at Instapundit: “It was probably militant feminists driven berserk by the name ‘Manly’ Ferry.” You never know, these days, you never know.
