Gunmen kidnapped Tuesday the member of the High Council of State (HCS) Mustafa Al-Treki from Matrad area in western Al-Zawiya city.
Social media loyal to Khalifa Haftar said the kidnap was 'a critical operation' for forces affiliated with Haftar, taking Al-Treki to Sorman and then Sabratha - the main foothold of Haftar's forces in western Libya.
The HCS issued a statement on Wednesday condemning the kidnap of Al-Treki from his house by an armed group loyal to "Dignity Operation of Khalifa Haftar".
It called in concerned authorities to exert all needed efforts to release the kidnapped member of the HCS, blaming the kidnappers for any harm that happens to Al-Treki.
"This incident is a violation of all laws and a threat to the efforts that aim at building a democratic and civilian state in Libya with freedom of speech and opinion." The statement reads.
Last May, Haftar's forces kidnapped the HCS member Mohammed Abu Ghamja from his house in Qasir Benghashir. His whereabouts are still unknown.
In July, Haftar's forces also kidnapped the member of the House of Representatives from her house in Benghazi. Her whereabouts are still unknown, despite reports that she was feed last month and is now suffering from bad psychological state.
