A pair of Iraqi tribes in the province of Missan are feuding over a nightingale a member of one tribe allegedly stole from the other, locals say. The Azzaman newspaper reported the theft of the nightingale has led to calls for violence from the tribe that owned the bird due to a violation of its \"tribal honor.\" The newspaper said surrounding tribes are attempting to smooth the ruffled feathers and prevent violence from breaking out while the chieftains of the two tribes are planning a summit to discuss the issue. Tribe members said any settlement reached between the chieftains would have to involve the return of the bird and the payment of \"a generous ransom.\"
