The Himanta Biswa Sarma-led Assam government will host a mega event to celebrate the upcoming Rongali Bihu where 11,000 dancers will perform in presence of Prime Minister Narendra Modi here on April 14, officials said. The spectacle, expected to be the largest in the Northeast in terms of the congregation of more than 10,000 Bihu dancers, may make an entry into the Guinness Book of World Records. Besides the prime minister, invitations for the event, to be held in Guwahati's Sarusajai indoor stadium, are being extended to all governors, chief ministers, union ministers, diplomats of G20 member nations and ASEAN countries, and other dignitaries.
