(CNN) -- Somalia's Al-Shabaab rebel movement has tightened its ties to the al Qaeda terror network, with its leader pledging loyalty to al Qaeda leader Ayman al-Zawahiri.
The Islamist militants control much of southern Somalia and have long been affiliated with al Qaeda. But in an audio message posted on Al-Shabaab's website Thursday, the Somali group's leader, Mukhtar Abu al-Zubair, tells al Qaeda leader Ayman al-Zawahiri that his followers "will march with you as loyal soldiers."
