Afghan authorities say a suicide car bombing targeted a NATO-led International Security Assistance Force (ISAF) convoy in Afghanistan's capital, Kabul, on October 13.
An ISAF spokesman said there were no ISAF casualties.
Deputy Interior Minister Ayoub Salangi tweeted on his official account that one person was killed and three were wounded.
It was not clear if the victim of the attack was the bomber himself.
General Farid Afzali, head of the criminal police in Kabul, said one Afghan civilian was wounded in the blast.
The attack occurred on the Jalalabad Road, a main thoroughfare where a U.S. military base and a UN housing compound are located.
Taliban spokesman Zabihullah Majahid claimed responsibility on Twitter, saying that the target was a foreign military convoy.
