An armed group in Libya has stormed the headquarters of the Great Man-Made River (GMR) project in the central-western area of Jabal al-Hasouna and reportedly kidnapped a group of workers, including foreigners, according to a Libyan security official.

Libya's east-based Interior Minister Ibrahim Bu Shaf has confirmed the report, Afrigate News said.

The privately-owned Afrigate News website quoted a security source as saying that the gunmen broke into the GMR offices earlier on Friday, 6 June, before the kidnapping took place.

They released the Libyan workers, but not the foreign nationals, the source said.

The foreign workers are reportedly from an unspecified Asian country.
