PARIS (AP) — Cement group LafargeHolcim says its chief executive officer is resigning, weeks after the multinational acknowledged that its branch in northern Syria had struck deals with armed groups so that it could keep business there running. The statement did not mention the internal investigation into the Syria branch, which the company in March acknowledged funneled money to armed groups in 2013 and 2014 to guarantee safe passage for employees and supply its plant.
