Al-Qaida's second-in-command says the United States failed to kill him with an airstrike earlier this month in Pakistan.
In a videotape broadcast Monday on Arabic language al-Jazeera television Ayman, al-Zawahiri says the attack killed several of those he calls innocents.
Al-Zawahiri asks President Bush if he knows where to find him. He answers the question himself, saying he is among "the masses of Muslims" and enjoying their support and protection.
Al-Zawahiri also says the United States ignored a truce offer made by al-Qaida leader Osama bin Laden in an audiotape broadcast two weeks ago if American forces withdraw from Iraq and Afghanistan.
The White House flatly rejected the offer of a truce, saying the United States does not negotiate with terrorists.
