CAIRO, Oct 8 (Aswat Masriya) - An Egyptian criminal court renewed on Thursday the detention of two men who have been under preventive detention for over 600 days for wearing anti-torture T-shirts, according to the Association for Freedom of Thought and Expression's (AFTE) official website.

Mahmoud Mohamed and Islam Talaat's detention has been renewed for 45 days pending investigation to reach a total of 666 days of incarceration.  

The prosecution had accused them of belonging to a terrorist organisation, possessing explosives and inciting violence. 

The two students, aged 19 and 21, were arrested in 2014 on the anniversary of the January uprising for wearing shirts emblazoned with the words "nation without torture", according to AFTE.

Amnesty International has launched a campaign calling for the immediate release of Mahmoud Mohamed, describing him as a "prisoner of conscience".
