The incidents occurred in the eastern part regions. A grenade exploded during a commemoration ceremony, attended a large number of people in Degah Bur. Meanwhile an powerful explosion rocked the city of Jijiga, the capital of Ogaden and also targeted a crowd.

According to reports, at least five people were killed and dozens wounded by the attacks blamed on the Ogaden National Liberation Front, a separatist rebel group that fights for the separation of Ogaden from Ethiopia.

The militant group is responsible for most of the attacks that take place in eastern Ethiopia, the last one killing 74 people working for a Chinese company with activities in the oil field.

During the civil conflict and the “Red Terror” Mengistu ordered the execution of thousands, most of them young people, partisans of the country’s future regime Ethiopian People's Revolutionary Democratic Front.
