What’s the situation in Lebanon?
On top of the ongoing COVID-19 pandemic that has affected more than 5,000 of its people, Lebanon is currently under a major economic and political crisis.
The people have taken to the streets since last year to protest government’s ruling elite that has dominated politics for years and failed to address Lebanon’s economic crisis since its civil war (1975-1990).
Tension has also risen between Israel and Lebanon’s militant political party Hezbollah, in a border conflict that had Israeli officials thwarted an attempt by Hezbollah to infiltrate its territory, just last week.
Several blasts have occurred in Lebanon, one of which resulted in the assignation of former prime minister Rafik al-Hariri by a truck bomb in Beirut on Feb 14, 2005. The long-awaited verdict of the assassination is due this week as four Hezbollah members are on trial in absentia at a special court in the Netherlands.
A two-week state of emergency has just been declared in the capital with the handing of security measures to the military.
