"The international community, especially the U.N. Security Council and Arab League, must act immediately to stop this massacre," Erdogan's office said in a statement.

"Turkey is deeply concerned about the armed intervention against civillian, peaceful demonstrations in Egypt. "We deeply regret the hundreds of deaths and thousands of casualties that occurred following the violent intervention in Egypt" he added.

Turkish FM urged Egypt's government

Turkish Foreign Minister Ahmet Davutoglu also urged Egypt's interim government to stop the police assault on Egyptians immediately, saying, "the assault on civilians protesting and showing their democratic reactions in a peaceful way is unacceptable."

FM Davutoglu is holding talks with counterparts following police move in Egypt to disperse by force the sit-in staged by supporters of ousted President Morsi.

Davutoglu is following the latest developments in Egypt closely, said diplomatic sources.
