The United States blasted Russia on Thursday over the bombing of Syria’s Eastern Ghouta, saying it has a “unique responsibility” for the more than 400 deaths in the Damascus suburb. After fresh air and rocket strikes by Syrian government forces killed another 46, State Department Spokeswoman Heather Nauert blamed Russia for not reeling in the regime of its ally President Bashar al-Assad. “Without Russia backing Syria, the devastation and the deaths would certainly not be occurring,” Nauert told journalists.
