An errant attack by US warplanes in Deir ez-Zor on Sept. 17 that killed 62 Syrian soldiers marked the beginning of the end of a short-lived US-Russia agreement to provide humanitarian relief to Syrians, jump-start political talks and coordinate targeting against terrorist groups.
Russian Foreign Minister Sergey Lavrov said that he found it “very hard to believe” that the United States could make such a mistake in Deir ez-Zor, where Syrian forces were battling Islamic State (IS) militants, adding that he had, however, conveyed an apology on behalf of the United States to Syrian President Bashar al-Assad.
