(CNN) -- A long-running dispute between two large tribes in Egypt burst into armed violence, with at least 18 people slain, the nation's news outlets reported Saturday.
The clashes that unfolded Friday between families of the Al-Halayel and Al-Dabodeya tribes took place in a district east of Aswan City. Police eventually restored order.
Ahram Online and MENA reported 18 deaths. Nile state TV reported 23 killed. Dozens have been injured.
Egypt, wracked with political unrest over the past three years, has had its share of longstanding tribal feuds as well.
