Prime Minister David Cameron said he was "saddened" to hear of Sky News cameraman Mick Deane's death in Egypt.
Mr Cameron wrote on Twitter:
I am saddened to hear of the death of cameraman Mick Deane, covering Egyptian violence. My thoughts are with his family and @skynews team.
Whether undercover in North Korea or exposed on Bosnian roads, Mick Deane ensured we left at the right time. This time he couldn't get out.
A British cameraman was killed in Cairo while covering clashes between supporters of Mohamed Morsi and Egyptian security forces.
