Osama's son urges overthrow of Saudi rulers
Osama bin Laden's son Hamza in an audio message has urged citizens of Saudi Arabia to overthrow their rulers and join al-Qaeda in the Arabian Peninsula (AQAP) in Yemen. AQAP was formed after the Yemeni and Saudi branches of al-Qaeda merged in 2009. This message comes after reports suggesting Hamza's increasing prominence compared to current al-Qaeda leader Ayman al-Zawahiri.
