An Afghan official says a bomb has killed a senior provincial intelligence official at his home in a remote northeastern corner of the country.

Mohammed Zahir, spokesman for Nuristan's governor, said the province's deputy intelligence chief Faiz Mohammed died Saturday. It wasn't immediately known how the bomb was detonated but Mohammed was the only casualty.

No one has claimed responsibility for the bombing but Taliban insurgents have been targeting U.S.-backed government officials, calling them puppets and traitors.

Afghanistan's intelligence chief Asadullah Khalid was badly injured in a suicide bombing in Kabul in December. The Taliban took responsibility for that attack.
