Without taking Tharoor's name, the chief minister sought an apology and withdrawal of the statement.
"Nagas have rich heritage&vibrant culture.We are proud of our history&traditions. The Naga headgear is renowned&gifted with honour,definitely not outlandish. Mutual respect makes India a great nation. One must apologise & withdraw statements that hurt others sentiments," Rio said on Twitter.
"You see him in Naga headgears with feathers. You have seen him in various kinds of extraordinary outfits which is a right thing for a prime minister to do. Indira Gandhi has also been photographed wearing various kinds of costumes. But why he still always says no to one?" Tharoor said at a seminar in Thiruvananthapuram yesterday.
His comments drew a sharp response from Union minister Kiren Rijiju, who said the Congress leader's remarks insulted tribals and people from the North-East.
"I demand apology from the Congress Party for insulting the people of India's North East & Tribals. Shashi Tharoor described North-East people & Naga Tribal headgears as funny looking outlandish & hilarious," Rijiju, a native of Arunachal Pradesh, said on Twitter.
"Shashi Tharoor insults the proud cultural heritage of the people of North-East. This condescension & arrogance towards the people of India have become hallmarks of @INCIndia," Union Information and Broadcasting Minister Rajyavardhan Rathore tweeted.
"For Shashi Tharoor, Naga headgear is outlandish and hilarious. In his over zealous love for skull cap, Tharoor doesnt mind insulting d customs of d Nagas n other NE people," he said.
Tharoor had recently kicked up a controversy with remarks that the BJP, if voted to power again, would rewrite the Constitution and pave the way for creation of a "Hindu Pakistan".
