Egypt's crackdown on Muslim Brotherhood - in 60 seconds

Some 528 supporters of Egypt's ousted Islamist President Mohammed Morsi have been sentenced to death, convicted of charges including murdering a policeman and attacks on people and property.

Authorities have cracked down harshly on Islamists since Mr Morsi was removed by the military last July, and the group is among some 1,200 Muslim Brotherhood supporters on trial.

BBC News puts the crackdown in context - in 60 seconds.
