Police say gunmen have kidnapped seven Pakistani engineers working in eastern Afghanistan.

The engineers were working on a hospital construction project in the Pul-e-alam district of Logar province.

Authorities say the Pakistanis were abducted at gunpoint Wednesday as they returned home after work.

No group has claimed responsibility for the kidnapping.

Elsewhere in Afghanistan, a roadside bomb killed three Afghan police officers in the northeast province of Baghlan on Thursday.
