Three explosions in the Ethiopian capital of Addis Ababa today severely injured four people, police said.
One blast hit a restaurant in the southern part of the city, extensively damaging the structure. The restaurant manager said the explosion was caused by a bomb planted in a flower pot outside. Four pedestrians were injured.
The other explosion struck a market, also in the south of the city. Police said the device was hidden in a rubbish bin. There were no injuries.
A third blast later went off outside the gate of a hotel and tourism training centre in the centre of the city. No one was injured in the blast, which damaged a small guard hut at the gate.
Ethiopia has been hit by a series of violent protests in which more than 80 people have died since elections in May, which the opposition says were rigged.
Top opposition Coalition for Unity and Democracy leaders were among 131 people charged with treason and planning to commit genocide stemming from the protests.
In January, several public buildings and hotels in Addis Ababa were damaged by explosive devices planted by unknown people.
