On 22 November, al-Shabaab militants stopped passengers on a Nairobi-bound bus and killed the 28 Kenyans who could not recite the Muslim statement of faith known as the shahada .
Kenyan troops moved into Somalia in October 2011 to try to establish a buffer zone between the country and Kenya following a spate of cross-border attacks by al-Shabaab. But the mission appears to have backfired, with the militants able to cross the border at will and carry out attacks in Kenya. Some in Kenya blame corrupt police officers and immigration officials for allowing the militants across the border.
