This looks like the work of Woyanne. Opposition groups do not target civilians.

(Reuters) — An explosion on a minibus shook central Addis Ababa today, killing three people and wounding nine, Ethiopian police said.
All the dead and wounded were on the bus, police said.
“Three people were killed and nine seriously injured by an explosion from a device planted by suspected terrorists inside a minibus taxi,” said Addis Ababa police spokesman Densash Hailu.
The blast on a road between the Hilton hotel and the foreign ministry was the latest in a string of explosions in Addis Ababa that Ethiopia has blamed on extremists backed by its neighbour and rival Eritrea.
Scores of policemen and soldiers rushed to the scene, cordoning off the area as fire engines arrived.
