Regime shelling on a medical center in northwestern Syria killed a woman Wednesday, in the latest in a long list of government attacks on health facilities, the Syrian Observatory for Human Rights said. The pre-dawn shelling in Marayan hit a building housing one of the few health centers in this part of Idlib province, it reported. An AFP photographer saw men salvaging medical equipment from the damaged two-story building on the ground floor, where the health center was located. The wife of the center’s director, who lived on the destroyed first floor of the same building, was killed by the shelling, the Observatory said. In recent days, regime and allied forces have ratcheted up their attacks on parts of the Idlib region still controlled by opposition groups. Four civilians, including a young woman and a child, were killed on Tuesday in rare artillery fire on the provincial capital of Idlib, the UK-based war monitor said. The Idlib region, which is home to about three million people and borders Turkey, is the last pocket to oppose Damascus in the decade-old conflict.
