In a video posted on the internet, a man reputed to be al-Qaeda’s deputy leader says Osama bin Laden is still alive and leading the terror group’s violent campaign. The interview with Ayman al-Zawahri appeared on a website frequently used by Islamic militants.The propaganda tape appears to have been made during or after last September as al-Zawahiri refers to elections in Egypt and Afghanistan. In it he also urges militants to attack Western oil interests in Islamic countries. The authenicity of the footage has not been verified. It appears to be the first confirmation for a year from a top al-Qeada member that bin Laden is alive. He and al-Zawahri are believed to have been hiding in the border regions of Aghanistan and Pakistan since the aftermath of the September 11 attacks in 2001.
