Foreign Secretary Nirupama Rao has ruled out scaling down New Delhi's operations in Afghanistan. Addressing the Widrow Wilson Centre, a Washington based think- tank, she said India is taking all necessary security measures to safeguard Indians living there. Terming it a barbaric attack against Indians engaged in humanitarian and development work in Afghanistan, she said, February 26 attack was by those who do not wish any other future for Afghanistan except one that suits their sinister ambitions.The Foreign Secretary said International community should understand that such attempts, if unchecked, would only embolden the same forces that held sway in Afghanistan in the 1990s and caused the tragedy of 9/11. On Iran, Ms Rao said India is opposed to any sanctions on Teheran that would have a direct impact on the common people of the country. She hoped the issues between Iran and the international community will be resolved through dialogue.
