U.S. military strikes on chemical weapons sites in Syria are “positive concrete steps” but not enough, Turkish President Recep Tayyip Erdoğan said on April 7.

“We find this [operation] positive as a step against the al-Assad regime’s war crimes committed with chemical and conventional weapons. But is it enough? I don’t see it as being enough,” Erdoğan said at a rally in the border province of Hatay.
