Tanweer, speaking with a Yorkshire accent, is seen in the video wearing a Muslim headscarf and jabbing his finger at the camera.
In an apparent message to the British Government, Tanweer vows that the attacks will continue until troops are pulled out of Iraq and Afghanistan and "you stop your support" for America and Israel, according to ITV.com .
"What you have witnessed now is only the beginning of a series of attacks that will continue and increase in strength until you withdraw your soldiers from Afghanistan and Iraq, and until you (the British government) stop your financial and military support for America and Israel," Tanweer said, speaking in English.
The 22-year-old suicide attacker killed seven people and himself aboard a London Underground train. All four of the suicide bombers were British.
At the Tanweer family home in Beeston in West Yorkshire, 200 miles north of London, a sign was posted in the window telling members of the media to stay away.
Irshad Hussain, a friend of the family, said the bomber's relatives would be "devastated" to see the video of Tanweer.
