Saleme made the remarks in an interview with AFP news agency, noting that there was “deadlock” in fighting in south Tripoli between Haftar’s Libyan National Army and the internationally recognized government.
“After the very first successes of the Libyan National Army two weeks ago, we are witnessing a military deadlock,” he said.
The latest fighting in Libya broke out earlier this month, as both sides seek control of the country.
According to the World Health Organization, at least 205 people have been killed since the war begun, with over 900 wounded.
Libya has experienced a political crisis since the 2011 ouster and killing of former leader Muammar Gaddafi.
The chaos enabled the breeding of various militant groups, including human trafficking rings that made the North African country a preferred departure point for migrants seeking to reach Europe.
Following the latest eruption of violence in the country, U.N. humanitarian agency OCHA last week warned of “disproportionate and indiscriminate use” of explosive weapons in densely populated areas.
