Osama Bin Laden's second-in-command, Egyptian-born Ayman al-Zawahri, delivered a video eulogy for the former al-Qaeda chueftain that was posted on YouTube today.

Zawahri promised that Al Qaeda would continue its jihad, or holy war, against non-Muslims invading Muslim lands.

He also criticized the US government for Bin Laden's burial at sea, deemed by some Muslim scholars as a violation of the shariah, or Islamic law.

He also called Pakistani rulers traitors for complying with the US' search for Bin Laden.

Zawahri called on Pakistanis to rise up against their leaders.

US military forces, together with Afghan militia forces, had been searching for Osama Bin Laden for about a decade since the September 11th attacks on the World Trade Center before they eventually located him in a mansion just outside of Islamabad, Pakistan.

Locals not only knew of his whereabouts, but reported that they had a good relationship with the terrorist mastermind.

The Muslim world saw some backlash after the US Navy SEAL attack responsible for killing Osama was announced in a public address by US President Barack Obama in May. One bomb blast in Peshawar, Pakistan killed a woman and three children and injured 11.

It is believed that the Al Qaeda network is currently in the process of regrouping and choosing its next leaders.
