Erdoğan says Turkey will do 'whatever it takes' to prosecute Egypt for Mursi's death

Mohammed Mursi's death was actually a murder, Turkish President Recep Tayyip Erdoğan said Wednesday.

"Mohammed Mursi was unfortunately convulsing on the floor of the courtroom for 20 minutes. Authorities there did nothing to intervene. Mursi's death wasn't from natural causes, he was murdered," Erdoğan said during a speech in Istanbul.

Morsi, Egypt's first freely-elected president, died after falling into a coma inside his soundproof glass cage during his trial on "espionage" charges.

Abdullah al-Haddad, whose father and brother were standing trial alongside Morsi, said security forces left the former president "slumped on the floor" of his cage for more than 20 minutes.

"We will closely follow the relevant process. We will do whatever it takes for Egypt to be tried in international courts. We call on the Organization of Islamic Cooperation (OIC) to take responsibility."
