Arab parties in Israel’s parliament have condemned the recent designation of the Iranian-backed Lebanese Hezbollah group as a terrorist organization by several Gulf Arab states.

Two parties from the Joint List, an alliance of Arab-backed parties, on Monday criticized the move by the Gulf Cooperation Council.

Prime Minister Benjamin Netanyahu responded by asking they would respond when Hezbollah fires rockets at their communities. Hezbollah fired thousands of rockets at Israel in 2006, when the country fought a war with the militant group in Lebanon. Hezbollah’s chief recently threatened to strike a chemical facility in Israel.

The parties drew anger last month after meeting relatives of Palestinians who killed Israeli civilians.

Israel’s Arab minority enjoys full citizen rights but often face discrimination in areas like unemployment.
