One Indian nun was among 16 people killed in strife-torn Yemen's Aden city on Friday when a group of terrorists stormed an elderly care home run by Kolkata-based Missionaries of Charity, handcuffed the victims before shooting them in the head.
Although initial reports suggested that four Indian nuns had been killed, it was later confirmed that only one nun identified as Cecilia Minj died.
The terrorists, numbering between 2 and 4, asked the guard to open the gate of the elderly home on the pretext of visiting their mothers. On entering inside, they first shot dead the gate keeper and then started shooting randomly at the inmates, officials in India's camp office in Djibouti said.
They said the attack at the care home in Sheikh Othman District in Aden took place at around 12:30 pm, killing at least 16 persons, including one Indian nun.
"The assailants escaped soon after the attack. The area has been cordoned off and the police are investigating the incident," the officials said.
In New Delhi, External Affairs Ministry Spokesperson Vikas Swarup said government was trying to find out details of the Indians killed in the attack.
"We are trying to ascertain the details of the Indian victims," he said.
In the wake of escalation of violence, Indian Embassy in Yemen's capital Sana'a was closed last year and all its functions were carried out from a camp office in Djibouti, a country neighbouring Yemen and across the Red Sea.
Al-Qaeda and ISIS have been stepping up attacks in Aden.
Two gunmen surrounded the home while another four fighters entered the building, an AFP report quoted witnesses and officials.
They said the gunmen moved from room-to-room, handcuffing the victims before shooting them in the head.
One nun who survived and was rescued by locals said that she hid inside a fridge in a store room after hearing a Yemeni guard shouting "run, run."
There are around 80 residents living at the home, which is run by Missionaries of Charity, an organisation established by Mother Teresa. Missionaries of Charity nuns also came under attack in Yemen in 1998 when gunmen killed three nuns in the Red Sea port city of Hodeida.
