Kabul, Feb.8 (ANI): Two Americans were among four persons killed on Sunday by a bomb blast in Afghanistan's southern Helmand province.
Police officials were quoted as saying that the Taliban was behind the attack.
The other two died were an Afghan interpreter and a policeman.
Police officials said that the group was checking an improvised explosive device on Sunday in the Nad Ali district that they believed had been defused.
The International Security Assistance Force confirmed there had been a remote-controlled explosion in the district but said first reports were only that an Afghan was killed and another wounded.
The US embassy also said it could not confirm the casualties. (ANI)
