Reuters staffers were given the option to work from home today after being told a "non-specific threat" was received. Sources say the threat was not directed at Reuters specifically, but that given the significance of the date — said to be a possible date of the London terror plot to blow up passenger planes headed towards the United States — the company felt it was appropriate to give employees the option to work remotely. It has not been disclosed how many employees opted to work from home.

A Reuters spokeswoman declined to comment on details of the threat or how it was communicated to Reuters. She said it is company policy to not comment on security issues.
