Grave sites destroyed in Somalia

Al Jazeera has obtained footage of Al-Shabab fighters in Somalia destroying grave sites and exhuming bodies before hiding them.The graves belong to foreign soldiers and a Sufi scholar. Al Shabab says it wants to rid Somalia of anything that does not fit with its strict version of Islam, but that has put it on a collision course with Sufi fighters. Al Jazeera's Zeina Awad reports.
