Nationwide protests paralyzed Lebanon on Friday as demonstrators blocked major roads in a second day of rallies against the government’s handling of a severe economic crisis and the entire country’s political class. The protests were the largest since 2015, and could further destabilize a country already on the verge of collapse and with one of the highest debt loads in the world. The protests could plunge Lebanon into a political crisis with unpredictable repercussions for the economy, which has been in steady decline for the past few years.
