A suicide bombing in Afghanistan's eastern Nangarhar Province has killed five people.
Nangarhar governor's office spokesman Attaullah Khogyani said the incident occurred shortly after security forces arrested nine Russian-speaking foreigners, including a woman and three children late on December 10.
Khogyani said the group was transferred to a security forces office when the woman who had been arrested detonated explosives strapped to her body.
The three children and one Afghan intelligence officer were killed in the blast.
There was no immediate claim of responsibility for the attack.
An investigation is under way on the remaining members of the group that was detained.
