Rumours say that Abiy has sent Cagjar to Hargeisa to request support in its war effort against TPLF.
I think Muse Biihi has a golden chance to offer mediation between the two warring sides. Somaliland has had good relations with TPLF and it is has a good relationship with Abiy Ahmed, Hargeisa could bring to two sides to Hargeisa for talks.
