FILE - In this March 3, 2021 file photo, Mounir Hujairi, 23, holds up a Lebanese national flag as walks in front of burning tires set on fire to block a main road, during a protest in downtown Beirut, Lebanon. It's an expression of anger but also of helplessness: Dense palls of smoke rising around Beirut and other parts of Lebanon from burning tires that anti-government protesters are using to block roads. The tactic has become the hallmark of a new flare-up of demonstrations against an intransigent political class that does nothing as its country slides toward the political and economic abyss.
