War crimes judges on Tuesday sentenced a former Islamist rebel who admitted wrecking holy shrines during Mali's 2012 conflict to nine years in prison, in the first such case to focus on destruction of cultural heritage.

Human rights groups and international legal experts hope Ahmad al-Faqi al-Mahdi's case in the International Criminal Court may serve as a deterrent to a kind of devastation that continues to be a feature of global conflicts yet has gone largely unpunished.

Al-Mahdi expressed remorse for his involvement in the destruction of 10 mausoleums and religious sites in Timbuktu dating from Mali's 14th-century golden age as a trading hub and center of Sufi Islam, a branch of the religion seen as idolatrous by some hard-line Muslim groups.
