The Ethiopian government has sent a high-level delegation to Eritrea for talks with the rebel Oromo Liberation Front (OLF), the official Ethiopian News Agency reports.

The delegation is led by Foreign Minister Workneh Gebeyehu and Oromia State Governor Lema Megersa, and is due to meet OLF leader Dawud Ibsa.

The OLF has not yet accepted Prime Minister Abiy Ahmed's call to all foreign-based opposition groups to return home and pursue their aims by peaceful means.

The OLF has been fighting for the self-determination of people in Ethiopia's Oromo region.

Until June, the rebel group had been on Ethiopia's list of banned terrorist organisations.

Much of the political unrest in the country has centred on the Oromo region, where people have complained about political and economic marginalisation.
