Reuters- Turkey has reminded Russia and Iran of their responsibilities in preventing violations of a ceasefire in Syria after a suspected chemical attack thought to have been carried out by Syrian government forces, Turkey's foreign ministry said on Wednesday.

Turkey had made representations to the Russian and Iranian embassies in Ankara over Tuesday's attack in the rebel-held province of Idlib, foreign ministry spokesman Huseyin Muftuoglu said in a statement.
