A new al-Qaida videotape posted Sunday on a militant Web site featured a short, undated clip of a weary-looking Osama bin Laden praising martyrdom.

The bin Laden clip, which lasted less than a minute, was part of a 40-minute video featuring purported al-Qaida fighters in Afghanistan paying tribute to fellow militants who have been killed in the country.

Bin Laden glorified those who die in the name of jihad, or holy war, saying even the Prophet Muhammad "had been wishing to be a martyr."

The authenticity of the video could not be verified, but it appeared on a Web site commonly used by Islamic militants and carried the logo of as-Sahab, al-Qaida's media production wing. It was not immediately clear when the video of bin Laden was filmed.
