India will continue its development and medical assistance in Afghanistan but will not send its troops, Defence Minister Nirmala Sitharaman asserted on Tuesday after a meeting with visiting US Defence Secretary James Mattis. "There shall not be any Indian boots on the ground in Afghanistan," Nirmala Sitharaman said at a joint press conference with her US counterpart, ruling out troop contribution amid America's emphasis on greater participation by India in the war-torn nation.
