US Deputy Secretary of State William Burns has held talks in Cairo with Egypt’s caretaker leaders.
He met interim President Adly Mansour and Prime Minister Hazem al-Beblawi, as well as the head of the armed forces, General Abdel Fattah al-Sisi.
He said the US remained committed to an Egypt that was “stable, democratic, inclusive and tolerant”.
Large numbers of protesters from both sides again gathered in Cairo, to coincide with Mr Burns’ visit.
According to Reuters news agency, security forces fired tear gas after supporters of ousted President Mohammed Morsi scuffled with locals.
