Hamza bin Ladan declared the call through a video message published by Al Qaeda-linked As-Sahab media on Wednesday, Site intelligence group reported.
In the video, he has urged Saudi people to join the Yemen-based Al Qaeda in the Arabian Peninsula to gain the necessary experience to overthrow Saudi Regime and decrease American influence in the region.
Though Osama Bin Ladan was born in Saudi Arabia, Yemen is his ancestral birthplace.
He was killed in 2011 by an elite American military team in Pakistan.
Ayman al Zawaheri now leads Al Qaeda group, but experts believe Hamza bin Laden aims for the position.
