New Zawahiri video

Al-Jazeera has just aired few minutes ago a new video by Dr. Ayman al-Zawahiri, Osama bin Laden's aide, where he accused the US army of conducting a "massacre against civilians in Kabul" last month. He also called up on Afghanis to support the "mujahideen" in their fight against Western military presence.
Al-Jazeera said it obtained the video from the internet.
