Abdul Hakeem Belhadj, leader of the Al-Watan party, speaks during an interview with Reuters in Tripoli March 4, 2015. Belhadj, an influential Islamist supporter of Libya's self-declared government, said United Nations talks were the only way to end the country's conflict, but signalled a deal would be hard while a rival government works with a former ally of Muammar Gaddafi. His remarks illustrate how support for U.N. sponsored negotiations may be complicated by divisions within the two loose alliances of Libyan forces now competing for power. Four years after the civil war that ousted Gaddafi, the North African country is caught up in conflict between two rival governments and their armed forces fighting to secure control over the OPEC member's oil wealth.

Belhadj, an influential Islamist supporter of Libya's self-declared government, said United Nations talks were the only way to end the country's conflict, but signalled a deal would be hard while a rival government works with a former ally of Muammar Gaddafi. His remarks illustrate how support for U.N. sponsored negotiations may be complicated by divisions within the two loose alliances of Libyan forces now competing for power. Four years after the civil war that ousted Gaddafi, the North African country is caught up in conflict between two rival governments and their armed forces fighting to secure control over the OPEC member's oil wealth.
