BEIRUT (AP) — The Syrian military has rushed in reinforcements to push back insurgents from advancing farther into the northern Hama countryside after they seized Aleppo in a surprise offensive. The insurgents look over most of Aleppo on Saturday and claimed to have entered the city of Hama. There was no independent confirmation of their claim. Iranian Foreign Minister Abbas Araghchi travels to Syrian capital Damascus later Sunday. He told reporters that Tehran will back the Syrian government and army. The swift and surprise offensive is a huge embarrassment for Syria’s President Bashar Assad and comes at a time when his allies — Iran and its groups and Russia — are preoccupied with their own conflicts.
