N'DJAMENA, Chad (AP) — At least 42 people were killed in eastern Chad after a clash between two families over a water point escalated into a cycle of reprisals, the country’s deputy prime minister said late Sunday.

Limane Mahamat said during a visit to the village of Igote, in the Wadi Fira province, where the clashes occurred on Saturday, that 42 people were killed and 10 wounded. He said those injured were evacuated to the provincial health center.

Mahamat said the cycle of reprisals had spread over a fairly large area, prompting an intervention by the army.
