A delegation of tribal leaders from eastern Libya has authorised the Egyptian military to intervene to protect Libya's sovereignty, Egypt says.
The tribal figures had earlier had talks in Egypt's capital, Cairo, with President Abdel Fattah al-Sisi.

In recent months he's suffered a string of battlefield defeats
