Charbel Wehbe, a member of Lebanon's caretaker government whose portfolio was taken over by Defence Minister Zeina Akar, suggested on Monday that Gulf states had supported the rise of Islamic State, among other disparaging comments.
Saudi Arabia, the United Arab Emirates, Kuwait and Bahrain summoned Lebanon's ambassadors and issued formal complaints.
The comments have threatened Lebanese efforts amid its deep economic crisis to improve ties with Sunni Muslim Gulf states, which have been reluctant to offer the kind of financial help they once did because of their frustration at the rising influence of Hezbollah, a Lebanese group backed by Shiite Iran.
