Morsi, ousted by the military in 2013 after one year in office, collapsed in a courtroom while facing a trial on Tuesday.
“I strongly condemned the repeated irresponsible accusation by the Turkish president about Egypt,” Sameh Shoukry said in a statement.
Erdogan accused Egyptian authorities of failing to take action to save Morsi’s life after his collapse in a Cairo courtroom on Wednesday.
“Morsi was struggling on the floor in the courtroom for 20 minutes. Authorities, unfortunately, did not intervene to save him,” Erdogan said in a televised speech in Istanbul.
He further said, “Morsi was killed. He did not die of natural causes.”
On Wednesday, Egypt government also accused the United Nations of trying to “politicise” the death of the country’s first democratically-elected president Mohamed Morsi by calling for an “independent inquiry”.
