EU foreign policy chief Federica Mogherini warned the Turkish government on Monday against taking steps that would damage the constitutional order following a failed weekend coup.

"We are the ones saying today rule of law has to be protected in the country," she said in Brussels. "There is no excuse for any steps that takes the country away from that."
