Yemeni security officials say gunmen have stormed a retirement home in the southern city of Aden, killing 16 people, including four Indian nuns.
The officials say that the gunmen raided the home for the elderly on Friday, separating the nuns from the others and then shooting them. They later handcuffed the elderly people and opened fire.
The officials spoke on condition of anonymity because they were not authorised to speak to the press.
The home is located in the Sheikh Osman district in Aden.
Aden descended into lawlessness after a Saudi-led coalition recaptured the city from Shia Houthi rebels last summer.
Islamic State has claimed responsibility for a wave of deadly attacks in Aden, including a suicide bombing that killed the governor and several assassination attempts on top officials.
