Sudan's former intelligence chief, detained for an alleged plot to sabotage national security, has been taken to hospital with heart trouble, his brother said on Thursday.

Salah Gosh was one of 13 people arrested on November 22. 

"We fear for his life because he already had heart problems and now he is in the hands of his enemies," Gosh's brother Abdelaziem Abdallah told AFP news agency.

AFP reports that Gosh’s wife and two daughters were allowed to visit him at Al-Amal Hospital.
