CAIRO (Reuters) - Egypt summoned the Turkish charge d'affaires on Saturday for the second time in a month to complain about comments by Prime Minister Tayyip Erdogan deemed insulting to the leadership in Cairo, the Egyptian Foreign Ministry said. In an interview with broadcaster CNN, Erdogan repeated the phrase that caused offence last time, calling Egypt's president, former army chief Abdel Fattah al-Sisi, a "tyrant".
