Outside the Journalists' Syndicate in central Cairo, about 200 protesters chanted "down with military rule", the signature slogan of the 2011 Arab Spring uprisings. The deal to hand over two islands in the Straits of Tiran, signed during a visit by Saudi Arabia's King Salman to Cairo last week, has provoked a storm of criticism against Egyptian President Abdel Fattah al-Sisi.
