At least four people were killed and 11 wounded in northwest Ethiopia's Bahir Dar town on Friday, in deadly street violence between security forces and opposition demonstrators, police said.

Police said in a statement that several policemen and soldiers also sustained wounds and physical injuries.

The statement said the violence in Bahir Dar was "sparked" by the "leadership" of the largest opposition Coalition for Unity and Democracy (CUD), adding that it was "put under control by the joint efforts of the police and security forces."

Meanwhile, local residents said police and soldiers clashed with demonstrators, who demanded the release of senior members of the CUD.

It is reported that on Friday there was also violence in the country's towns of Awasa, Gondar, Dessie and Dire Dawa.

Since Tuesday, CUD members and supporters took to the street over the contested results of the May 15 parliamentary election, leading to bloodshed between riot police and protesters in the country's capital Addis Ababa. At least 24 civilians and 7 police officers died in clashes, according to city police.
