Afghan police say unidentified gunmen in northwestern Pakistan have kidnapped an Afghan government advisor as he visited relatives in a border town.

Authorities say an adviser to the Afghan Ministry of Rural Development, Akhtar Kohistani, was abducted from his in-laws' house or wife's relatives' house in Chitral, Pakistan, late Sunday.

No group has claimed responsibility for the abduction.

The kidnapping is the second of a prominent Afghan in Pakistan in the past four days.

On Friday, the brother of Afghanistan's finance minister was kidnapped in northwest Pakistan as he visited family members.

Officials say the businessman Zia ul-Haq Ahadi was abducted by unidentified assailants in a residential area of Peshawar.

And, in September, Afghanistan's top diplomat to Pakistan was kidnapped in the same neighborhood. He has yet to be released, and authorities are searching for him.
