An official says two Chinese engineers and four Afghans have been kidnapped by gunmen in northwestern Afghanistan.

Abdul Sattar Barez, the deputy provincial governor of the Faryab province, says the six men were seized late Saturday while travelling back to their base after a day working on a road construction project.

He said on Monday that nobody has claimed responsibility for the kidnapping. The four Afghans included two engineers and two drivers.

Afghan police and intelligence services are searching for the men, who have not been identified for security reasons.
