According to Josh Butler, associate editor of Huffington Post Australia, "many hundreds" of compromised accounts – including @Forbes, @BBC America, @Atlanta_Police, @CBSTVStudios, @Bieber_Japan, sports teams and other verified users – tweeted the message in Turkish overnight.

The tweet, which begins with a swastika and includes a YouTube link, "says 'Nazi Germany' and 'Nazi Holland' and 'see you April 16th,'" Butler tweeted.

Third-party application Twitter Counter confirmed at 4:55 a.m. ET that it had been hacked and was investigating the issue.
