Turkish President Recep Tayyip Erdogan has criticized Egypt for sentencing ousted President Mohammed Morsi to death, saying the country was returning to the "old Egypt" by rolling back democracy.

Erdogan on Saturday also criticized western nations that he accused of not speaking out against Egyptian President Abdel-Fattah el-Sissi, who ousted Morsi, or against death sentences being handed down to Morsi's Muslim Brotherhood group.

Turkey's government strongly supports the Muslim Brotherhood. Relations between Egypt and Turkey soured after Morsi's ouster by el-Sissi.

On Saturday, an Egyptian court sentenced Morsi to death over his part in a mass prison break that took place during the 2011 uprising that toppled Egypt's long-time leader Hosni Mubarak.
