MORONI, April 27 (Reuters) - Politicians and civil society groups on the coup-prone Indian Ocean archipelago of Comoros on Saturday protested against an attempt to destabilise the government and warned that people linked to an infamous mercenary were at the heart of the plot.
Comoros authorities said there was a conspiracy to undermine the country's rulers and last week arrested around 10 people for alleged involvement in the attempt to destabilise the government.
Disquiet has simmered in recent months on the politically volatile archipelago, which has experienced around 20 coups or coup attempts since independence in 1975, after President Ikililou Dhoinine sacked people allied to his predecessor.
Although the opposition initially criticised the authorities for keeping details about the plot a secret, on Saturday opposition party leaders, the president's party and civil society groups marched around the capital city Moroni to protest against the attempt to destabilise the impoverished country.
Houmed Msaidie, head of the opposition, said a government briefing suggested Patrick Klein, who worked under the notorious French mercenary Bob Denard, was "one of the main authors of this destabilisation attempt". Klein could not be contacted to answer the allegations.
Denard, who died in 2007, stalked Comoros for around 30 years and was involved in four coups on the islands. He also led ruthless, often ill-disciplined bands of European ex-soldiers, sometimes dubbed "Les affreux", or "the terrible ones", in wars in Yemen, Biafra and Congo.
Zahara Toyb, a Mouroi party activist, said the march was organised "to call a halt to mercenaries who aspire to stop stability and peace in my country." Around 1000 people attended.
Independent information can be hard to access in the tightly controlled country made up of three small volcanic islands and there is still little known about last week's plot.
Arrests of high-profile individuals, including the son of former President Ahmed Abdallah Abderemane, who was assassinated in 1989, as well as a former minister, Mahmoud Ahmed Abdallah, have left Comorans with more questions than answers.
