( CNN ) -- Al Qaeda leader Ayman al-Zawahiri urged people in Saudi Arabia to follow the example set by popular revolutions in Egypt , Libya and Tunisia and rise up . `` Why do n't you rise up , for you are the sons of the strong and proud tribes that look down upon death in order to lift up humiliation and oppression ? Are you afraid of the forces of the Saudi regime and its security and army ? '' al-Zawahiri said in a video posted Thursday on jihadist forums , according to the SITE Intelligence Group . It 's the latest video message from al-Zawahiri , who took over as leader of the terror network after Osama bin Laden was killed by U.S. forces . In recent days , al-Zawahiri has made a similar call on the people of Yemen , saying the government was a puppet of the United States . In the 6-minute , 19-second video , al-Zawahiri called on the people of Saudi Arabia to overthrow their rulers , saying they committed criminal and un-Islamic activities , said SITE , an organization that tracks the online activity of terror groups . Al-Zawahiri questioned how people could watch the Arab Spring revolutions and do nothing . In the video , he said Saudi Arabia 's rulers should be ousted for , among other things , opening the country to American forces and jailing militants . `` The Family of Saud might be able to kill tens , hundreds , or thousands from amongst you , but if hundreds of thousands come out , then they will be shocked and will end up , Allah permitting , in the state that their brethren ended up in amongst the ousted tyrants , '' he said , according to SITE 's translation . Al-Zawahiri was al Qaeda 's No . 2 leader under bin Laden . He took over leadership in June 2011 following bin Laden 's death , according to statements posted on jihadist websites . One of the FBI 's most wanted terrorists , al-Zawahiri has played a defining role in al Qaeda . He was indicted for his alleged role in the August 7 , 1998 , bombings of the United States Embassies in Dar es Salaam , Tanzania , and Nairobi , Kenya , that killed 224 civilians and wounded more than 5,000 others , according to the National Counterterrorism Center , part of the U.S. federal government . The FBI is offering a $ 25 million reward for information leading to his capture , the same amount as the reward for bin Laden . Al-Zawahiri 's wife and three children were killed in December 2001 in a U.S. attack on the family 's residence in Afghanistan . Al-Zawahiri is believed to be hiding somewhere in Pakistan 's tribal region that borders Afghanistan . CNN 's Chelsea J. Carter contributed to this report .
