Sri Lanka's Foreign Minister Lakshman Kadirgamar has been fatally shot by unidentified snipers near his tightly guarded residence in the capital, Colombo. Local police say the 73-year-old veteran minister died early Saturday at Colombo's National Hospital, where he was taken for emergency surgery after being shot in the head. There was no immediate claim of responsibility for the shooting, but Sri Lankan authorities blame Tamil Tiger rebels. The shooting comes amid escalating tensions between the government and the rebels, who have been threatening to resume a two-decade civil war. Mr. Kadirgamar was from the Tamil minority and was a close aide of President Chandrika Kumaratunga. He led efforts to ban the rebels as a terrorist organization.
