CAIRO - Egypt on Tuesday urged US authorities to exercise restraint in dealing with racially charged demonstrations in Ferguson, Missouri - echoing language Washington used to caution Egypt as it cracked down on Islamist protesters last year.

It is unusual for Egypt to criticize such a major donor, and it was not immediately clear why the government would have taken such a step.

Ties between Washington and Cairo were strained after Egyptian security forces killed hundreds of Muslim Brotherhood supporters following the army's ousting of freely elected President Mohamed Morsi in July 2013.

Western allies have voiced concern about the democratic credentials of President Abdel Fattah al-Sisi, the army chief who toppled Morsi and went on to win elections. The United States has, however, continued to provide military and other support to Cairo.

The Egyptian Foreign Ministry's statement on the unrest in Ferguson read similarly to one issued by US President Barack Obama's administration in July 2013, when the White House "urged security forces to exercise maximum restraint and caution" in dealing with demonstrations by Morsi supporters.
