( Sky ) - Al Qaeda leader Osama bin Laden is to release a new video in which he declares war on Pakistani President Pervez Musharraf and the Pakistani army, according to an Islamist website.
Bin Laden with al ZawahiriThe announcement of the upcoming message came as the terror group released a new video in which bin Laden's deputy boasted that the US was being defeated in Afghanistan, Iraq and on other fronts.
The messages are part of a stepped-up propaganda campaign by Al Qaeda around the anniversary of the September 11 terror attacks.
Earlier this month, bin Laden released two messages - including his first new appearance in a video in nearly three years.
A banner posted on the Islamic militant website said: "Urgent: Al Qaeda declares war on the tyrant Pervez Musharraf and his apostate army, in the words of Osama bin Laden."
The 80-minute video released on the same site was in the style of a documentary.
A speech by bin Laden's deputy, Ayman al Zawahiri, was interspersed with footage from the 9/11 attacks, interviews with experts and officials taken from Western and Arab television stations and old footage and audiotapes of bin Laden.
Al Zawahri began by condemning the Pakistani military's July assault on Islamic militants who took over the Red Mosque in Islamabad.
He paid tribute to one of the militants' leaders, Abdul Rashid Ghazi, who was killed in the fighting.
"The siege revealed the extent of the despicableness, lowliness and treason of Musharraf and his forces, who don't deserve the honour of defending Pakistan, because Pakistan is a Muslim land, whereas the forces of Musharraf are hunting dogs under Bush's crucifix," al Zawahri said.
"Let the Pakistani army know that the killing of Abdul Rashid Ghazi and his male and female students has soaked the history of the Pakistan army in shame and despicableness which can only washed away by retaliation."
