Two Christian men have been shot dead after an Easter vigil in the south of Egypt, security sources say.
Another Coptic Christian was reported injured in the attack near the village of Qena.
Police are searching for four Muslim men suspected of having carried out the shooting, which is thought to have been the consequence of a family vendetta.
A security source quoted by Reuters said those killed had recently been freed from prison for killing a Muslim.
Vendettas are common among clans in southern Egypt, being pursued equally bitterly within faith communities as between Christians and Muslims.
Coptic and Orthodox Christians marked Easter on Sunday, a week later than their Catholic and Protestant counterparts.
Copts account for about 10% of Egypt's 80 million population.
