The Media Foundation for West Africa (MFWA) has called on transitional and constitutional governments in Burkina Faso, Mali, Niger and Guinea to end arbitrary arrests and prolonged pretrial detention of journalists and civil society actors. The MFWA made the demand in its report launched at the regional conference on press freedom and democratic governance in West Africa held in Abuja on Tuesday, adding that this was part of urgent measures to reverse the deteriorating state of media freedom and freedom of expression across the four countries.
