Sri Lanka's President Mahinda Rajapaksa (L) shakes hands with Army Commander Lieutenant General Sarath Fonseka after arriving in the northern town of Kilinochchi April 16, 2009 during a one-day visit to the defence force based in the war-torn north of the country. Sri Lanka's two-day humanitarian truce ended on Wednesday and the military announced it was now free to begin a final assault to end the 25-year war against the rebel Tamil Tigers. The Sri Lankan military says only 1,000 Liberation Tigers of Tamil Eelam (LTTE) rebels remain, and accuse the fighters of holding around 100,000 civilians as human shields.
