Hackers have compromised the main Twitter account of The Associated Press, sending out an erroneous tweet about an attack at the White House.
The tweet, which said that there had been two explosions at the White House and President Barack Obama was injured, came after hackers made repeated attempts to steal the passwords of AP journalists.
According to the Washington Post, the tweet said, "Breaking: Two Explosions in the White House and Barack Obama is injured."
The AP said Tuesday that its Twitter account had been suspended following a hack and said it was working to correct the issue.
The cyberattack is the latest in a string targeting international media organizations.
The tweet put out by hackers briefly sent the Dow Jones Industrial Average sharply lower. It plunged more than 128 points following the tweet, but quickly recovered, reports USA Today.
On Saturday, a group that calls itself the "Syrian Cyber Army" took credit for a similar attack on the official Twitter accounts of CBS's shows "60 Minutes" and "48 hours," according to Boston.com. It is not clear if the attacks are related.
