The last one was apparently aimed at Western audiences. On the 6th anniversary of 9/11, Bin Laden aims his latest video message at Muslims.
From Al Jazeera:The video begins with a photograph of bin Laden in front of a brown backdrop.
In a voiceover, he is heard saying: "His talk of mine consists of some reflections on the will of a young man who personally penetrated the most extreme degrees of danger and is a rarity among men: one of the 19 champions, may Allah have mercy on them all."
"We shall come at you from your front and back, your right and left," al-Shehri said in the tape, asserting that the US would suffer the same fate as the former Soviet Union.
In the tape, al-Shehri also praised the losses the United States suffered in Somalia in the late 1990s.
"As for our own fortune, it is not in this world," he said. "And we are not competing with you for this world, because it does not equal in Allah's eyes the wing of a mosquito."
In a tape released on Friday, bin Laden had mocked the US as "weak" and threatened to escalate the war in Iraq.
News of the latest video emerged before the US was to hold ceremonies to remember the dead from New York's Twin Towers, the US defence department headquarters in Washington and a hijacked jet that crashed into a field in Pennsylvania.
More from the Associated Press:In the tape, bin Laden praised al-Shehri, saying he "recognized the truth" that Arab rulers were "vassals" of the West and had "abandoned the balance of (Islamic) revelation."
"It is true that this young man was little in years, but the faith in his heart was big," he said.
"So there is a huge difference between the path of the kings, presidents and hypocritical Ulama (Islamic scholars) and the path of these noble young men," like al-Shehri, bin Laden said. "The formers' lot is to spoil and enjoy themselves whereas the latters' lot is to destroy themselves for Allah's Word to be Supreme."
"It remains for us to do our part. So I tell every young man among the youth of Islam: It is your duty to join the caravan (of martyrs) until the sufficiency is complete and the march to aid the High and Omnipotent continues," he said.
At the end of his speech, bin Laden also mentions the al-Qaida leader in Iraq, Abu Musab al-Zarqawi, who was killed in an U.S. air strike there. Al-Zarqawi followed in the footsteps of al-Shehri and his brothers who "fulfilled their promises to God."
"And now it is our turn," bin Laden says.
After bin Laden speaks, the video of al-Shehri appears. Al-Shehri — one of the hijackers on American Airlines Flight 11, which hit the World Trade Center — is seen wearing a white robe and headscarf, with a full black beard, speaking in front of a backdrop with images of the burning World Trade Center.
