UK Foreign Secretary Philip Hammond said that the reported airstrikes conducted on hospitals in northern Syria in recent days could amount to war crimes and must be investigated. In a statement issued today, he said: "I am appalled that the Assad regime and its Russian supporters are still bombing innocent civilians despite the agreement last Thursday to a cessation of hostilities and even as the UN Envoy for Syria is in Damascus trying to relieve the killing and suffering." "I call on all parties to commit to making rapid progress towards a cessation of hostilities, humanitarian access and negotiations towards a political transition, as agreed at last week's meeting of the International Syria Support Group in Munich. There must be a major change in behavior by the Syrian regime and its supporters if the agreements reached in Munich are to become a reality. Russia's tactics are making a political settlement - and therefore the defeat of Daesh - even harder to achieve," he concluded.
