Libya was plunged into fresh turmoil this week after a car bomb killed eastern military intelligence chief Fawzi al-Mansouri in Benghazi, drone attacks struck the country’s largest operational oil refinery and the central bank governor resigned from his post. Mansouri, the military intelligence chief for forces controlling eastern Libya, was leaving a mosque on Monday night when an explosive device attached to his vehicle detonated, the Libyan National Army (LNA) said on Tuesday. Khaled Haftar, the son of the LNA renegade commander Khalifa Haftar who controls eastern Libya, said authorities had opened an investigation, adding that "indicators point to a despicable terrorist tactic". The turmoil deepened after a letter attributed to Central Bank of Libya Governor Naji Issa circulated widely on social media and local news outlets. Blackouts have triggered protests in Tripoli, Zawiya, Misrata and other cities, where demonstrators have demanded reliable power and called for Dbeibah to resign.
