In a landmark achievement and a proud moment for the nation, an Indian Army mountaineering team from Eastern Command has successfully summited Mount Kangto (7,042-metre)--the highest and hitherto unconquered sentinel peak of Arunachal Pradesh--approaching from the challenging Southern route, a release said.

This accomplishment marks the first recorded successful ascent of the formidable Mount Kangto, long regarded as an unclimbed guardian of the Kameng Himalayas, the Army said in the release on Friday.
