The August 2010 West Bank shooting attack was an attack near the Israeli settlement of Kiryat Arba in the Israeli-occupied West Bank, carried out by Hamas militants. Four Israeli settlers from the settlements of Beit Hagai and Efrat were killed after gunmen attacked their vehicle. It was the deadliest Palestinian attack on Israelis in over two years. The assailants were arrested by the Palestinian Authority but promptly released after Hamas accused the authority of treason. On 8 October, Israel arrested militants connected with the attack in a raid in which two Hamas operatives were killed.
