India will continue to value fundamental freedoms and will emerge stronger in the face of the terrorist attacks in Mumbai, Indian Ambassador to Japan Hemant Krishan Singh said Tuesday.

"I can assure you that the most intensive of investigations are ongoing on what really was behind these heinous terrorist attacks," Singh said in a speech at Aoyama Gakuin University in Tokyo.

About 170 people, including 38-year-old Japanese businessman Hisashi Tsuda, were killed during last week's coordinated terrorist attacks in the Indian financial capital.
