Turmoil In African Nation Of Mali Continues

Melissa Block speaks with Jennifer Cooke, director of the Africa program at the Center for Strategic and International Studies, about the deteriorating situation in Mali. Islamic militants in recent days have destroyed sacred tombs in the ancient city of Timbuktu. A military coup there in March created a power vacuum, allowing the rebel and Islamist groups to take over the northern part of the country. West African leaders this past weekend urged Mali's interim government to request outside military assistance.
