Libyan fighters reject new head of army

Two of Libya's former rebel groups have rejected the governments choice of a new head of the armed forces, Yousef Mangoush, which has raised fresh concerns over the security in the country.

In his first international interview, Mangoush told Al Jazeera he understands the challenges he faces in his new role.

Yet not everyone is convinced with his credentials, and convincing the rank and file that he is the man to lead them may be hard. Already brigades from the east of the country have rejected his appointment, preferring someone from their own city to represent them.
