Puri, Sep 11 (ANI): To commemorate the 13th anniversary of the 9/11 attacks, renowned sand artist, Sudarshan Pattnaik, sculpted the twin towers of World Trade Centre on the beaches of Puri, with the message 'No Terror, but Peace.' Pattnaik created a five feet high sand replica of the twin towers representing the number eleven, in the middle of the number nine. The sculpture was made using five tonnes of sand and took about seven hours to complete. Pattnaik said he was concerned about the growing incidents of terror today, 13 years after what is regarded as one of the worst terror strikes the world has seen.
