Liyuu police attacked them first in their own towns and the Oromos responded by killing Somalis in Oromia. It wasn't Oromo police but Qeero, the people behind the uprising in Ethiopia. There's no need for backlash against the Oromo refugees in Somaliland who've harmed no one and fleeing agazi hit squads. Illey deported all the Oromos in kililka shanaad and the ones who returned, some were killed by Tigrey army. Leave them be, they're suffering too.
