Islamist rebels in Somalia have warned neighboring Kenya against invading border areas under their control in the southern part of the Horn of Africa country, local media reported on Thursday. In the past weeks, the Islamist group of Al Shabaab was accused by the Kenyan government of orchestrating rally riots in support of Abdulah Al-Faisal, an radical Jamaican cleric, who had once been jailed for allegedly inciting hatred against non-Muslims. He managed to enter Kenya recently and the authorities have since sought to deport him. Sheikh Mohamed Arab, the Islamist-appointed Governor of Dhobley town on the common frontier between Somalia and Kenya, told the local Shabelle radio that '1,500 Kenyan soldiers were amassed' at the border and that there were military maneuvers by Kenyan troops. The Islamist official accused the Kenya troops of planning an invasion of territories under the group's control, vowing to defend their 'country' to the last drop of blood. The extremist group which controls much of the southern and central part of Somalia had previously threatened to invade Kenya in retaliation for its support to the Somali government. The movement is blamed for a number of cross border raids into Kenya's border towns and abductions of Kenyan and foreign citizens. It praises the violent demonstrations staged in Nairobi on Friday by supporters of the Jamaican cleric, saying it is a religious duty to do so. Some of the demonstrators were reportedly waving the black flag of the Somali insurgent group of Al Shabaab, prompting the Kenyan security crackdown on Somalis in the Nairobi suburb for the perpetrators of riot near Jamia Mosque in Nairobi.
