Police officers responding to reports of a gun battle in the Arab village of Ilut in northern Israel themselves came under fire late on Saturday night.
Police said shots were fired at officers from close range by suspects wielding handguns after officers arrived in the town to end the armed confrontation between two feuding families.
The shots prompted the norther police district chief Cmdr. Roni Atiya to hold a special meeting with commanders, during which he heard that officers had nearly been struck by the bullets. The meeting concluded with a decision to launch a wave of arrests.
Police raided dozens of addresses in the hours that followed, arresting 22 people. Several homes were searched, including the home of the Ilut Regional Council head.
