E/CN.4/1991/17 page 47 142. On 4 December 1990 the Government of Saudi Arabia described the allegations referred to above as "wrong, inaccurate and exaggerated". In particular, regarding the case of the Yemeni citizen Muhammad Kashi Ayash Bin Zayd, it was affirmed that "the statement narrated by the said person is groundless". It was further stated that no sentence had ever been issued in the history of the kingdom of Saudi Arabia to amputate an arm. "The Islamic law stipulates that only the hand is amputated if the accusation is proved and following a confession of the guilty. Moreover, the hand is amputated after several repetitions of the crime and especially of valuables". Somalia Urgent appeals 143. On 3 August 1990 the Special Rapporteur sent an urgent appeal to the Government of Somalia concerning Mohamed Ahmed Jama, Zeinab Yusuf Omar, aged 28, Abdullahi Yusuf Omar, (Zeinab Yusuf Omar's brother) aged 30, and 16 unnamed persons. They were reportedly arrested on their arrival at Mogadiscio International Airport on 22 July 1990 after they had been returned to Somalia by the Italian authorities which refused their entry to Italy, and detained at Godka prison. In view of several reports in the past that detainees suspected of opposition to the Government were tortured at Godka prison, fears were expressed that the above-mentioned persons might be at risk of torture and ill-treatment. Letters 144. On 6 June 1990 the Special Rapporteur addressed a letter to the Government of Somalia transmitting information alleging that Mohamoud Mohamed Mohamoud, aged 18, a student from Mogadiscio, was arrested on 9 or 10 February 1990 by security officers and interrogated, allegedly under torture, about the flight from the country, in July 1989, of his elder brother who was suspected of anti-Government activity. On 11 February, Mohamed Mohamoud was admitted to Digfer Hospital in Mogadiscio in a coma. He died the next day. According to eyewitnesses he had blood coming out of his ear. South Africa Urgent appeals 145. On 5 February 1990 the Special Rapporteur sent an urgent appeal to the Government of South Africa concerning Peter Mokaba, President of the South African Youth Congress, who was detained on 27 January 1990 in Seshego township near Pietersburg, reportedly by South African police. Mr. Mokaba was said to be detained under section 29 of the Internal Security Act (ISA), under which a detainee could reportedly be held in solitary confinement for an unlimited period for the purpose of interrogation, without access to lawyers, family or doctors, other than State officials. Mr. Mokaba had previously been detained under Section 29 of the ISA from March 1988 to 25 June 1989 and he subsequently alleged that while he was held in incommunicado detention he was chained, assaulted and tortured by police.
