Yemeni officials have released CCTV of a militant attack that killed 52 people and left 167 wounded.

The attack on the attack on the Yemeni Defence compound on December 5 also saw gunmen firing at soldiers. The footage shows a man throwing a grenade at a group of people before running away.

A local branch of al-Qa'ida in Yemen claimed responsibility for the strike which is thought to be the worst in the country for 18 months.
