A charity group established by Mother Teresa says an Indian Catholic priest was abducted by militants when they attacked a retirement home in southern Yemen last week, killing 16 people including four nuns.

Missionaries of Charity spokeswoman Sunita Kumar said Monday in Kolkata that Father Tom Uzhunnalil was handcuffed and taken away by the attackers when they stormed the retirement home in Aden.

Indian External Affairs Ministry spokesman Vikas Swarup said there was no information about the priest's current location or status.

After they entered the retirement home, the gunmen moved from room to room, handcuffing their victims before shooting them in the head. Kumar said two of the killed Catholic nuns were from Rwanda and the other two were from India and Kenya.
