Egyptian prosecutors are demanding that three Al-Jazeera English journalists accused of supporting the Muslim Brotherhood get the maximum penalty of 15 years in prison.

Prosecutors gave their closing arguments on Thursday in the case against Baher Mohamed, Peter Greste and Mohamed Fahmy in a court in Cairo. The three journalists have been imprisoned since December and are accused of filming protests on June 30, 2013, in Tahrir Square in a manner that supported then-President Mohammed Morsi and his followers. The prosecution also said the journalists' reporting on sexual violence in the square negatively portrayed Egypt.

Abdullah Elshamy, another Al-Jazeera journalist who works for the Qatar-based channel, has been jailed since August and on a hunger strike since January.

The trial is part of a continuing crackdown by military authorities against the Muslim Brotherhood and supporters of ousted President Morsi.
