Ethiopia says Somalia helped in rebel leaderโ€™s โ€˜surrenderโ€™ (AP)

ADDIS ABABA, Ethiopia โ€” Ethiopia on Friday said a senior figure with the rebel Ogaden National Liberation Front has willingly surrendered, days after the group accused neighboring Somaliaโ€™s security forces of kidnapping and forcibly extraditing him.

Ethiopia foreign ministry spokesman Meles Alem told The Associated Press that Somalia โ€œplayed a facilitation roleโ€ in the surrender of Abdikarin Sheikh Muse.

The incident involving the ethnic Somali rebel leader has sparked outrage in Somalia, with some accusing the government of violating the constitution, which bars the extradition of Somali citizens to another country. Somaliaโ€™s government has not confirmed the extradition, and the intelligence chief has called it a โ€œsensitive matter.โ€

โ€œWe want an explanation from the government and which must give clarifications on who exactly has extradited the Somali national to the enemy by those who were supposed to protect him,โ€ said Zakariye Haji Mohamud, a Somali lawmaker.

It is not clear what nationality Muse holds. The Ethiopian ministry spokesman said he has Ethiopian citizenship.

ย The ONLF rebels seek the secession of Ethiopiaโ€™s ethnic Somali region and have waged an armed struggle against the government. Ethiopian lawmakers in 2011 labeled the ONLF a terror group alongside al-Qaida and al-Shabab. No senior member of ONLF had been detained in recent years.

In a statement issued on Wednesday, the rebel group said Abdikarin was arrested in the Somalia town of Galkayo, where he went to bring his young niece to the capital, Mogadishu, for medical treatment.
