The joint statement adds new emphasis to global concern over Russia's true aims in Syria - and whether it is concerned primarily with attacking the terrorist group ISIS or with propping up Syrian President Bashar al-Assad and protecting its military base in Syria.
"We express our deep concern with regard to the Russian military build-up in Syria and especially the attacks by the Russian Air Force on Hama, Homs and Idlib since yesterday which led to civilian casualties and did not target Da'esh," said the statement, jointly issued late Thursday by the U.S., UK, Turkey, France, Germany, Qatar and Saudi Arabia.
