Afghan police say a suicide bomber has killed at least two civilians and wounded four others in an attack near an American military base outside of Kabul.
Kabir Ahmad, chief of Bagram district of Parwan province, said a suicide attacker blew himself up on Monday near Bagram Air Field.
NATO had no immediate information on the attack.
Taliban spokesman Zabiullah Mujahid claimed responsibility, saying it was revenge for the recent burning of Qurans at the base.
The Taliban have been seeking to exploit the burning. Qurans were among books burned because they were said to contain messages from militants.
Also Monday, the Interior Ministry said one civilian was killed and 11 people wounded when a man blew himself up at a police checkpoint in Jalalabad in the east.
