It is the latest in a string of attacks on major media outlets including CBS News, The Guardian, the BBC, National Public Radio, Reuters and The Associated Press.

The Syrian Electronic Army said it seized control of several FT blogs and social media accounts, replacing the headline with “Hacked by Syrian Electronic Army.”
The messages have since been removed. The Financial Times responded on Twitter:
Apologies, we have been hacked and you may see tweets that are not from the FT. We are working on getting this fixed.

An FT spokesperson said the company was "working to resolve" the problems "as quickly as possible."
