The Islamic State group, which overran large areas of Iraq and Syria, has set up training camps in eastern Libya and the American military is closely monitoring, a top U.S. general said Wednesday.

An anti-Islamist former Libyan general, Khalifa Haftar, said Friday he has given himself two weeks to take Benghazi and three months to recapture the capital Tripoli.
