Atyrau Region Prosecutor Rakhimbek Mamyrbaev said 115 of the wounded required medical assistance and two were hospitalized.
Mamyrbaev told the Interfax-Kazakhstan news agency the fight involved over 300 Kazakh and 100 Turkish workers.
All the workers are contractors of the Tengizchevroil oil joint venture who are building a plant near the Tengiz oil field. Tengizchevroil said in a statement that the construction site will remain closed pending an investigation.
Prosecutors believe the fighting erupted when a Kazakh worker attempted on October 19 to cut into the queue at the company's cafeteria. The fight lasted several hours and a number of cars were reportedly burned.
