A suspected “price tag” attack was discovered Friday morning at a tree nursery in the Israeli Arab town of Kfar Kassem. The attackers cut down 30 trees, and left a sign reading “Greetings Esh Kodesh.”

The sign appeared to reference Tuesday’s incident in which 15 Israeli settlers were captured and held by Palestinians after they allegedly approached the village of Qusra in order to carry out an attack to protest the Israeli Civil Administration’s uprooting earlier in the day of an olive grove near the West Bank outpost of Esh Kodesh.

The settlers, said to have come from the outpost, claimed later they were merely out hiking. Some of them were beaten by their captors, and were handed over to the IDF after several hours.

Police opened an investigation into the Kfar Kassem incident.

Overnight, seven Israelis, including four minors, were arrested in connection with the incident in the Palestinian village of Qusra.

In an incident which at this stage appears not to be connected to Esh Kodesh, three men were arrested early Friday morning in Kibbutz Tirat Tzvi, near the Jordan border, on suspicion that they intended to damage the property of a senior inspector from the Israel Land Administration who lives on the kibbutz.

The three, aged 19-23, allegedly targeted the inspector, responsible for approving building in the northern West Bank, because he had distributed demolition orders for illegal structures in the West Bank.
