Baghdad: Al Qaida leader Osama Bin Laden's latest message about "foiling plots" in Iraq is going to be posted online, an Islamist website said on Friday.

The website did not say, however, when it would post Bin Laden's 56-minute message. It also did not say whether the new recording would be a video or audio clip.

"May God expose the cover-up by Al Jazeera, the channel of the infidels," a message on the website reads.

It was not clear whether this meant Bin Laden would speak about a controversy in which his supporters have accused the popular news channel of misrepresenting his comments on Iraq.

Some Islamists have said Al Jazeera misrepresented Bin Laden's views by airing excerpts of comments he made in October that insurgents had made mistakes in Iraq because of fanaticism.
