The Syrian rebel-held town of Khan Sheikhoun which was hit by chemical weapons last week, was targeted once again. Following a U.S. air strike that hit a Syrian air base in retaliation to the Assad regime, the northern Syrian town was hit again on Friday and Saturday. It still remains unclear who carried out the strikes, although Russia and Syria have been the only two countries bombing the rebel-held town. The attacks come after Tuesday's chemical attack left more than 85 people dead and hundreds more injured.
