Kenyan authorities believe three terrorism suspects detained at the weekend are potential suicide bombers who may be linked to this month’s murder of a British Broadcasting Corporation journalist in Somalia, a senior police official said on Monday.
The trio had documents detailing the fatal shooting on February 9 in Mogadishu of BBC producer Kate Peyton as well as other documents indicating that they had been trained to carry out suicide attacks, the official said.
In addition, the official, who spoke to AFP on condition of anonymity, said the three were believed to have ties to Osama bin Laden’s al-Qaeda network.
“They had documents detailing the killing of the BBC and documents that indicated they were trained suicide bombers,” the official said.
“The documents don’t say whether these men were actually involved in the murder but they give precise details of the killing,” the official said.
