Tribute to Sky cameraman killed in Egypt violence

Head of Sky News, John Ryley, has paid tribute to cameraman Mick Deane, who has been killed in violence in Egypt.

He described him as ''a lovely, lovely guy'' and ''an astonishingly good cameraman.''

Egypt's presidency has declared a state of emergency after scores of people died when security forces stormed protest camps in Cairo.

The camps had been occupied by supporters of former president Mohammed Morsi, who was deposed in early July.
