News of Ethiopian Army's Control over Mekele is not 'True'
Dr. Heba Al-Bishbishi, a specialist in African affairs, said on Sunday that the circulated news about the Ethiopian forces' full control of the Tigray region is not 'true'.
In televised statements to "Ala Masaolity" talk show aired on 'Sada ElBalad" TV channel, Al-Bishbishi added that Ethiopia has always been involved in internal military conflicts, especially with neighboring countries, without specific goals or tangible results.
Moreover, she pointed out that Ethiopian Prime Minister (PM) Abiy Ahmed is always trying to convince the international community that he preserves Ethiopia's independence from the tribal conflict.
''Ethiopia is witnessing a political conflict between disproportionate and dissonant tribes,'' she said, noting that the situation will not change unless Abiy's concept of federal rule changes.
She also added that The number of Ethiopian refugees streaming into eastern Sudan has now surpassed 40000 since the crisis began.
