The Libyan army, reinforced by gunmen loyal to Haftar, have been waging a street war since mid July, against Islamic militants in the city of Benghazi in an attempt to regain control of the city, which fell into the hands of Islamists since last July.
Benghazi was the birthplace of the 2011 protests that toppled Libya's former leader Muammar Gaddafi. The city has witnessed a drastic escalation of violence and became a major extremist base in North Africa since the US ambassador to Libya was killed in 2012.
