In northwestern Syria, dozens of people have been reported killed amid heavy airstrikes by Russian and Syrian warplanes. Among the dead are the parents and siblings of 2-year-old Khadija al-Hamdan, who was the sole survivor of an airstrike that flattened out her home in Idlib province. The U.K.-based Syrian Observatory for Human Rights says Syrian forces have dropped over a dozen barrel bombs in recent days on Idlib, backed by scores of Russian airstrikes which have hit schools and hospitals. The United Nations has called for an urgent de-escalation of fighting.
