Fresh air strikes pummelled the Syrian city of Aleppo on Monday as US Secretary of State John Kerry made a desperate bid to salvage a two-month ceasefire in the war-torn country. "The attack on this hospital is unconscionable," he said, accusing President Bashar al-Assad's regime of deliberately targeting three clinics and a major hospital last week. Kerry met UN peace envoy Staffan de Mistura and the Saudi foreign minister in Geneva, but the absence of Russia cast a pall over the proceedings.
