"It is time the communities and refugee leadership to be vigilant and think carefully about who they see," he said on Wednesday.

Speaking with Radio Xoriyo also known as Radio Freedom, he said Ethiopia exports its domestic problems to the neighboring countries like Kenya, Djibouti and Somalia whenever it feels the burden.

"For Ethiopia, it never be ashamed of attacking refugees mainly Ogaden, Anuak and Oromo community leaders that have fled from its army brutality as the case of the 2010 elections."

" For instance, when Ethiopian elections was happening in 2010, Ethiopian Security Forces attempted to kill activists, opposition figures and community leaders from Ogaden region, Oromia and Gambella," Sadik said.

Sadik added that EPRDF-dominated government will get elect itself and that nothing good expects to happen for the May 2015 election.

Sadik called on the government of Kenya to be aware activities of Ethiopian assailants and those conspiring with them to ensure that they would not harm any one without the knowledge of Kenya.

Human Rights Watch accused the Ethiopia's government of systematically cracking down on media ahead of the May 2015 election.

Ethiopia's Prime Minister Hailemariam Desalegn asked Turkish President Recep Tayyip Erdogan to act as mediator with the ONLF taking advantage of Erdogan's visit to Ethiopia, according to Africa Intelligence.

ONLF was founded in 1984, and it has been engaging army struggle with the Ethiopian troops stationed in Ogaden region since 1994, after the Ethiopian government cracked down its members, following after Ogaden parliament overwhelmingly voted yes for self-determination.
