At least 28 people are reported to have been killed in an air strike on a refugee camp in rebel-held northern Syria, monitors say.<br />The Syrian Observatory for Human Rights said the dead included women and children, and that the toll from the strikes, which hit a camp for internally displaced people near the town of Sarmada, was likely to rise.<br />Sarmada lies about 30km (20 miles) west of the city of Aleppo, where a cessation of hostilities brokered by Russia and the US had brought a measure of relief on Thursday.<br />But fighting continued nearby and president Bashar al-Assad said he still sought total victory over rebels in Syria.
