Islamic State militants say they are responsible for a blast that killed the governor of Yemen's port city of Aden.

Jaafar Mohammed Saad and several aides died when their convoy was hit. IS says it detonated a car laden with explosives as he drove by.

The group has established a presence in Yemen since its civil war broke out.

It is opposed to the government and Iranian-backed Houthi rebels who have seized much of the country, including the capital Sanaa.

Earlier this year, Aden was recaptured by government troops backed by a Saudi-led coalition.
