Timeline of the Syrian conflict as it enters 8th year
Syria’s conflict enters its eighth year Thursday, with President Bashar Assad’s forces fighting to drive rebels from their last bastion near the capital, Damascus, and Turkish forces closing in on the northern Kurdish-held enclave of Afrin.
Assad remains firmly in power seven years after an Arab Spring-inspired uprising that began with peaceful protests but escalated into an armed rebellion following a brutal government crackdown. Russia and Iran have provided massive aid to Assad’s forces, allowing them to advance on a number of fronts in recent years.
The Islamic State group was able to exploit the chaos to seize up to a third of the country at one point, but its self-declared caliphate is now in ruins, with the militants largely confined to a remote area along the Syrian-Iraqi border.
An al-Qaida-linked group dominates the northern Idlib province, while U.S.-backed Kurdish forces hold around a quarter of the country in the northeast.
The fighting in Syria has killed an estimated 400,000 people since 2011 and driven half the population from their homes, with more than 5 million becoming refugees, mainly in neighboring countries. Several rounds of peace talks have done little to stem the bloodshed.
A timeline of key events in the Syria war:
March 2011: Protests erupt in the city of Daraa over security forces’ detention of a group of boys accused of painting anti-government graffiti on the walls of their school. On March 15, a protest is held in Damascus’ Old City. On March 18, security forces open fire on a protest in Daraa, killing four people in what activists regard as the first deaths of the uprising. Demonstrations spread, as does the crackdown.
April 2011: Security forces raid a sit-in in Syria’s third-largest city, Homs, where thousands of people tried to create the mood of Cairo’s Tahrir Square, the epicenter of protests against Egyptian autocrat Hosni Mubarak.
