French President Francois Hollande on Tuesday accused Syrian leader Bashar al-Assad of responsibility for a ‘massacre’ after a suspected chemical attack killed at least 58 people in a rebel-held town in Syria. “Once again the Syrian regime will deny the evidence of its responsibility for this massacre,” Hollande said in a statement. “Those who support this regime can once again reflect on the enormity of their political, strategic and moral responsibility,” Hollande added.
