KHARTOUM: About 100 Sudanese journalists and activists staged a silent vigil on Thursday in support of a global campaign to support Al-Jazeera television journalists detained in Egypt.
"Working as a journalist is not a crime," said a banner held by the protesters who gathered on a street near the Qatar-based satellite channel'sandnbsp;Khartoumandnbsp;office.
The channel's local staff were among the demonstrators, who carried pictures of the four detained Al-Jazeera staff including Australian Peter Greste, Canadian-Egyptianandnbsp;Mohamed Fadel Fahmyandnbsp;and Baher Mohamed.
They have been held since December in a case that has sparked an international outcry.
Their trial began in aandnbsp;Cairoandnbsp;court last week, against the backdrop of strained ties between Cairo and Doha, which backed deposed Islamist presidentandnbsp;Mohamed Morsiandnbsp;and his now-banned Muslim Brotherhood.
Morsi was ousted by the army in July.
The government has designated the Brotherhood a "terrorist organisation", although the group denies involvement in a spate of bombings since Morsi's overthrow.
The journalists are accused of supporting the Brotherhood and broadcasting false reports, charges denied by the television network.
A fourth Al-Jazeera journalist, Abdullah al-Shami, has been held since August.
Al-Jazeera declared Thursday a "global day of action" in support of its staff and for media freedom generally.
Unusually for a protest in Sudan, no police were seen near the Khartoum vigil, which dispersed peacefully after about an hour.
Sudanese reporters have previously demonstrated against a lack of freedom in their own country, which ranked near the bottom, at 170 out of 179, in the Reporters Without Borders (RSF) 2013 World Press Freedom Index.
