A Hacked AccountThe Twitter account of The Associated Press was hacked on Tuesday and erroneously sent out a message saying there had been explosions at the White House, injuring President Obama.Within a few minutes, Twitter suspended the account, and Julie Pace, the chief White House correspondent for The A.P., announced at a White House briefing that the account had been hacked.*

ClarificationJay Carney, Mr. Obamas press secretary, confirmed that the president was unharmed.Editors at The A.P. soon followed with a statement saying that The @AP twitter account has been hacked. The tweet about an attack at the White House is false. We will advise more as soon as possible.*
