Egyptian President Abdel Fattah al-Sisi called on Middle Eastern nations to maintain stability just as tensions were suddenly spiking between Lebanon and Saudi Arabia. "The stability of the region is very important and we all have to protect it ... I am talking to all the parties in the region to preserve it," Al-Sisi said in an interview with CNBC over the weekend that aired Tuesday morning. On Saturday, Lebanese Prime Minister Saad al-Hariri shocked the political establishment in Beirut by announcing his resignation. The leader said he was stepping down amid concerns of a potential assassination plot against him. Speaking from Riyadh, Hariri criticized Iran, and its Lebanese ally Hezbollah, for igniting conflict in the region.

Following the CNBC interview, Reuters reported that Saudi Arabia sharply escalated rhetoric in the region by declaring that Lebanon had — figuratively at least — declared "war" against it because of aggression from Hezbollah. Saudi Gulf Affairs Minister Thamer al-Sabhan said the government of Lebanon "would be dealt with as a government declaring war on Saudi Arabia," Reuters reported. When asked whether the time had come for Egypt to consider its own measures against Hezbollah, Al-Sisi replied, "The subject is not about taking on or not taking on, the subject is about the status of the fragile stability in the region in light of the unrest facing the region." "The region cannot support more turmoil," he said.
