The Foreign Minister of Sri Lanka, Lakshman Kadirgamar, has been assassinated in the capital Colombo. Mr. Kadirgamar, who was 73, was a member of the country’s Tamil minority, but had in the past opposed peace negotiations for the Tamil Tiger’s separatist movement. Dumeetha Luthra reports from Colombo.
     The Foreign Minister Lakshman Kadirgamar was at his home when the attack took place. Officials say he was shot in the head at long range by a sniper. He was taken to hospital, but doctors were unable to save him. He was suffering from severe head and chest injuries. No group has said they are responsible, but the Tamil Tiger rebels are the main suspects. Security has been tightened around the capital with police checkpoints and helicopters circling overhead. Mr. Kadirgamar was a key figure in the government, and both the President and Prime Minister have visited the hospital.
