Started with protests in Daraa in 2011, the Syrian conflict rapidly turned into a war with a number of foreign powers supporting various militant groups (including al-Qaeda-linked) against the government of Bashar al-Assad. Since then, the country has been a point of instability in the Middle East.
Russia began a military intervention in Syria in 2015 after an official request by the Syrian government for military help against militant groups.This allowed the Syrian government to survive and to regain initiative in a battle against Hayat Tahrir al-Sham (formerly Jabhat al-Nusra, the Syrian branch of al-Qaeda), ISIS and other militant groups.
What is that airbase near Palmyra? Is it jirah?
Jirah is in the province of Aleppo. In the Palmyra countryside, the map shows the Palmyra Airbase and the T3 Airbase (east of Palmyra).
Oh right I forgot that jirah and deir hafer are way up north there lol thanks
