General Khalifa Haftar's loyal military forces obstructed Libya's interim Prime Minister Abdul Hamid Dbeibah's visit to the city of Ghat, Anadolu Agency reports.
Nasr Youssef, who represents Ghat in the parliament, said that the pro-Haftar militia prevented the visit, citing lack of prior coordination, according to the report.
He said Dbeibah's visit was aimed at studying the city's needs and addressing the challenges facing its residents.
Libya has been in turmoil since the 2011 NATO-backed uprising that ousted Muammar Gaddafi, and, after 2014, it was split between warring western and eastern factions.
General elections will be held in Libya on 24 December. The election was mandated by the Libyan Political Dialogue Forum, a UN-selected assembly that set a roadmap for peace in Libya, a major oil producer, through installing a unity government and holding a nationwide vote.
