Lebanese Prime Minister Saad al-Hariri said on Monday that the political and militant group Hezbollah must stop interfering in regional conflicts and accept a neutral policy to bring an end to Lebanon’s political crisis, Reuters reported.

The Iranian-backed Hezbollah, which forms part of the Lebanese government, is fighting alongside Syrian President Bashar al-Assad in Syria and in Iraq against Islamic State militants.

Gulf monarchies have accused the Shi‘ite group of also supporting the Houthi group in Yemen and of backing militants in Bahrain. Hezbollah denies any activity in Yemen or Bahrain.

Hariri’s main patron is Saudi Arabia, Iran’s main regional rival, which has also intervened in regional conflicts.

“I don’t want a political party in my government that interferes in Arab countries against other Arab countries,” Hariri said in an interview recorded on Monday with French broadcaster CNews.

“I am waiting for the neutrality which we agreed on in the government,” he said. “One can’t say one thing and do something else.”

Hariri shocked Lebanon on November 4 by resigning from his post in a statement from Saudi Arabia. His resignation, however, has not yet been accepted.

“Lebanon cannot resolve a question like Hezbollah which is in Syria, Iraq, everywhere because of Iran. It is a regional political solution that needs to be done,” Hariri said.

“I think in the interest of Lebanon, Hezbollah is carrying out a positive dialogue. They know we have to remain neutral in the region.”
