Detained Al Jazeera journalist's brother speaks out

The trial has resumed in Egypt of three journalists from the Al Jazeera television network, whose detention in December sparked an international outcry over press freedom.

The three men are accused of spreading false news and helping the banned organisation, the Muslim Brotherhood.

They deny the charges.

Andrew Greste - the brother of one of the accused, Australian journalist Peter Greste - told the BBC about the tough conditions his brother is facing in prison.
