Russia's defense ministry claims to have hit 12 ISIS targets after sending out 18 deployments over 24 hours, destroying terrorist camps, command points and communications hubs in the regions around Idlib, Hama and Aleppo.
Meanwhile, a joint declaration by the U.S., U.K., France, Germany, Qatar, Saudi Arabia, Turkey called for an "immediate" halt to all Russian military intervention which they say have yielded civilian casualties.
"These military actions constitute a further escalation and will only fuel more extremism and radicalization," the statement posted on the Turkish foreign ministry website read.
"We call on the Russian Federation to immediately cease its attacks on the Syrian opposition and civilians and to focus its efforts on fighting ISIL."
Russia has coordinated its attacks with the Syrian army — a move that's pitted the country against Western allies which have backed Syrian rebels and called for the resignation of President Bashar Assad, who's been accused of launching chemical attacks on his own people.
