Thousands of people protested in Egyptian cities today against Israeli air strikes on Gaza and Egypt's president pledged to support the Palestinian enclave's population in the face of "blatant aggression".

A complex system of air defences has been instrumental in protecting Israel's population from incoming rockets.
