LONDON -- The Financial Times says that several of its blogs and Twitter feeds have been compromised by hackers. The Syrian Electronic Army, a pro-government group which has repeatedly attacked Western media organizations, has claimed responsibility.

A few of the FT's dozens of Twitter feeds were compromised Friday and broadcast messages supporting Syrian President Bashar Assad. One described the Syrian rebel group Jabhat al-Nusra as terrorists and linked to a graphic video of a hooded man shooting kneeling prisoners in the back of the head.

The hackers have apparently spent much of the past 24 hours trying to break into the FT's system.

An internal company memo distributed Thursday and seen by the Associated Press warned FT employees not to click on suspicious emails.
