A German woman and an Afghan guard were killed by unknown gunmen Saturday night in Kabul, a spokesman for the Afghan Interior Ministry told CNN.
A Finnish woman was also abducted during the attack.
The attack happened at a compound that was housing employees of the Swedish charity, Operation Mercy. The organization issued a statement saying, "Our thoughts and prayers are with the families involved."
Finland's Ministry for Foreign Affairs confirmed the kidnapping Sunday and issued a statement saying "the identity of the kidnappers is not known." The motive for the attack also remains unclear.
"Finland urges [the] immediate release of the kidnapped person," the statement added.
The Guardian reports that the attackers slit the Afghan security guard's throat and then entered the house where they shot and killed the German aid worker.
Neighbors told Tolo TV that the aid workers were friendly and had lived in the house for several years.
“They had rented the house, they would leave the house in the morning and return at around 4:30 in the afternoon. They would wear our traditional clothes and headscarves, they were not armed and had two guards,” Abdul Jalil, a neighbor, told Tolo TV.
Kidnappings have been a threat to both foreigners and Afghans in the past. Often foreigners are kidnapped by organized criminal networks seeking a ransom. Becuase of the kidnapping threat, many nonprofit groups have moved into compounds to protect employees, according to The Guardian.
