AlQa'dah 12, 1433, Sep 28, 2012, SPA -- Kenyan troops invaded al-Shabab's last stronghold in Somalia on Friday, coming ashore in a predawn beach landing at Kismayo that appeared likely to deprive the insurgents of their last big money-making enterprise, AP reported. African Union troops from Kenya, Uganda and Burundi have combined over the last 18 months to kick al-Shabab out of the capital Mogadishu and take a series of smaller towns that the insurgents fled to. By Friday afternoon, Kenyan Defense Forces said that its ground troops were also steadily approaching Kismayo from the west. Al-Shabab, which is allied with al-Qaida, had earned money by collecting taxes on goods arriving at the Indian Ocean port, so the loss of the stronghold would be a double blow to the armed fundamentalist group that began attacks in 2007 and ultimately controlled all but a few blocks of the capital. -- SPA
