A Sudanese court has sentenced 27 intelligence agents to death for torturing and killing a school teacher early this year after he was arrested during protests.
It is the first time members of the security forces have been condemned to death in relation to the killing of protesters whose movement .
The defendants were found guilty of torturing to death Ahmed al-Kheir Awadh at an intelligence services facility and sentenced to be hanged, judge Sadok Abdelrahman said.

The teacher was beaten and tortured to death after he was arrested in late January by intelligence operatives in Kassala state in eastern Sudan, the judge said.
Dozens of protesters from the capital's teachers' association gathered in front of the court in Khartoum's twin city of Omdurman, carrying pictures of Awadh.
Defence lawyers have two weeks to lodge an appeal against the death sentences.
Sudanese first took to the streets just over a year ago, to protest against high bread prices, but the demonstrations soon turned into demands for Mr Bashir to step down.
The president was deposed in April by the military, but huge protests continued, culminating in a compromise that saw a joint military-civilian transitional council formed in August.
At least 177 people were killed in the repression of the months-long protests, according to rights group Amnesty International, while a doctors' committee close to the protest movement put the toll at over 250.
Many of those killed were the victims of a 3 June massacre outside army headquarters in Khartoum, perpetrated by men in military fatigues.
On the first anniversary of the protests, thousands of Sudanese citizens earlier this month took to the streets of Khartoum and other cities, in order to pay their respects to the "martyrs of the revolution".
Mr Bashir was on 14 December sentenced to two years in an elderly offenders' institution after being convicted in a corruption case.

The former president faces numerous other domestic probes, and he has long been wanted by the International Criminal Court for alleged crimes, including genocide, related to the conflict in Darfur.
The transitional administration inherited an enfeebled economy, which was battered by years of US sanctions under Mr Bashir, patronage and the secession of oil-rich South Sudan in 2011.
The first post-Bashir budget was unveiled by the government late Sunday. It envisages an increase in the deficit to 3.5 per cent of gross domestic product (GDP) in 2020, up from 3.3 per cent in 2019.
