A group of unidentified gunmen attacked on Friday an elderly care home in Yemen's main southern city of Aden, killing 16 people, including four Indian nurses, local sources said.

Four gunmen knocked the home care's door telling the guard that they wanted to visit their mother, but when they entered, they opened random fire at residents.

Medical sources said the death toll was expected to climb as many of the victims sustained serious injuries.
