(CNN) -- Al Qaeda leader Osama bin Laden will address the West in a new message, according to a banner ad from the group's production wing posted on Islamist Web sites known to carry messages from al Qaeda and bin Laden.
This image accompanied a message from Osama bin Laden in November.
"To the western nations, soon, God willing, A new speech by the Lion of Islam Sheikh Osama Bin laden, The reasons of the struggle in the 60th anniversary of the Israeli Occupation," the banner reads.
It was not known whether the message would be audio or video or when it might be posted. In the past, messages were available from an hour to two days after the initial posting.
Bin Laden's last message came March 20, when in an audiotape he called Iraq "the perfect base to set up the jihad to liberate Palestine."
In an audiotape released the previous day, bin Laden condemned European countries for siding with the United States in Afghanistan and for allowing the publication of cartoons considered insulting to Islam's prophet, Mohammed.
