Over the course of just eight days, a kind of mini world war played out inside Syria. Conflict intensified, involving major players like the U.S., Russia, Turkey, Israel and Iran. Kurds, rebel groups, and forces loyal to Syrian leader Bashar al-Assad also got involved. Here’s how one of the most chaotic weeks in the Syrian war unfolded. Saturday, Feb. 3. A Russian airplane is shot down over Idlib province, apparently by anti-Assad rebels. Sunday, Feb. 4. Pro-Assad forces bomb the same province. A suspected chemical attack is reported by doctors in rural Idlib. Rebels blame the Syrian regime. Monday, Feb. 5. Russians launch airstrikes targeting Eastern Ghouta, a rebel held area near the capital, Damascus, leaving more than 100 dead over the next several days. Tuesday, Feb. 6. The U.N. calls for a cease-fire, saying Syria faces an “extreme” humanitarian crisis. Syrians say Israeli warplanes fired missiles near Damascus. Fighting continues between Turks and Kurds in the Kurdish majority region of Afrin. And Turkey restates that from there, it will push 80 miles further into Manbij, a Kurdish-held city with a U.S. military presence. Wednesday, Feb. 7. Top U.S. generals visit an American base near Manbij, in what was seen as a direct message to Turkey, a NATO ally, to keep its distance. Pro-Assad forces attack U.S.-backed fighters in Eastern Syria. The U.S. launches a rare air assault in response. At least 100 pro-Assad troops, including Russian mercenaries, are presumed dead. Thursday, Feb. 8. Rebels and civilians continue to suffer withering air assaults in Eastern Ghouta. Some of the worst of the seven-year civil war. Saturday, Feb. 10. An Israeli F-16 crashes in northern Israel, after coming under heavy fire by the Syrian military. Israel said it had shot down an Iranian drone that entered its airspace after being launched from Syria. A Turkish helicopter is also shot down by Kurdish fighters. Two pilots are killed and seven other Turks die in fighting. It’s the highest one day death toll since the Turkish incursion in Syria. All of this played out against the backdrop of the continuing U.S. mission to defeat ISIS — a fight that remains ongoing, even as other conflicts arise.
