He also sent a pointed warning to the Iran-backed Shiite group Hezbollah, which was well represented in the outgoing government and some analysts accuse of holding up the process. Hezbollah should "not think it is more powerful than it is.... It must show that it respects all the Lebanese. And in recent days days, it has clearly shown the opposite," said Macron. Macron, who visited Lebanon twice in the wake of the explosion, had repeatedly urged the Lebanese not to waste any more time in forming a government. The August 4 explosion of hundreds of tons of ammonium nitrate at the Beirut port killed more than 190 people, wounded thousands and ravaged large parts of the capital. The disaster sparked new protests over corruption and mismanagement, prompting the previous cabinet to step down.
