Egypt's foreign ministry has summoned Turkey's ambassador to Cairo for the second time this month over what it described as a Turkish interference in internal Egyptian affairs.
An informed diplomatic source told Al-Ahram Arabic news website that the foreign ministry told Turkish ambassador Hussein Bostali that recent statements by Turkish officials on Egypt are a "breach of diplomatic customs and mutual respect."
The ministry regarded Bostali's remarks as a "clear intervention" in Egypt's domestic affair.
On Sunday, Turkish Prime Minister Recep Tayyip Erdogan, an outspoken supporter of Egypt's ousted president Mohamed Morsi, attacked the European Union and others for failing to condemn strongly enough the killing of dozens in Cairo on Saturday.
Eighty people were killed and hundreds injured when pro-Morsi demonstrators and police forces clashed at the Memorial of the Unknown Soldier in Cairo's Nasr City district on Saturday.
On 10 July, the foreign ministry summoned the Turkish calls for the United Nations (UN) Security Council to intervene in Egyptian domestic politics.
The ministry was referring to recent calls by Turkish officials for the UN to take action against what Ankara has called a "military coup" in Egypt after the army ousted Morsi on 3 July amid mass demonstrations against him.
In addition, Erdogan said in an interview with a Turkish newspaper earlier in July that "my president in Egypt is Morsi because he was elected by the people."
In response, Egypt's interim presidency and foreign ministry expressed their dissatisfaction at these comments.
