Turkish president says Morsi was killed

Turkish President Recep Tayyip Erdogan says former Egyptian president Mohamed Morsi did not die of natural causes but was killed.

During a speech in Istanbul, Erdogan said the deposed Egyptian president allegedly "flailed" in a Cairo courtroom for 20 minutes on Monday and nobody assisted him.

"Unfortunately, Mohamed Morsi was on the ground of courtroom flailing for 20 minutes. No official there intervened. Morsi did not (die) naturally, he was killed," Erdogan said on Wednesday.

The president said Turkey would do everything in its power to ensure Egypt faces trial in Morsi's death.

He also called on the Islamic Cooperation Organisation to "take the necessary action" over Morsi's death.
