A son of former Al-Qaeeda leader Osama Bin Laden, Hamza, has vowed revenge on the US for the death of his father.

Osama, the world’s most notorious terrorist for years after orchestrating the 9/11 terror attacks, was killed in 2011 by US Navy Seal Team Six in a raid on his hideout in Pakistan.

In a video posted online, Hamza, 28, calls on all his comrades to strike at the West, advising them to be relentless in executing their mission.

“Be perfect in your choice of targets, so that you may damage your enemies more.” Bin Laden said in the video, according to MailOnline.

“If you are able to pick a firearm, well and good; if not, the options are many. Take lead in inflicting losses, attacking the jugular of the enemy and hitting its joints.”

It is believed that Hamza is looking to take over leadership of the terror group, which has been led by Ayman al-Zawahiri since the death of his father in 2011.
