Along with crests and certificates, the first prize was Tk 50,000, second prize Tk 25,000 and third prize Tk 15,000.
After the ceremony, the three Hello journalists met bdnews24.com Editor-in-Chief Toufique Imrose Khalidi at the offices of Bangladesh’s first internet-only newspaper.
Hello, Bangladesh's first-ever specialised Bangla news website for children, is the result of a joint initiative between bdnews24.com and Unicef.
Children under the age of 18 are trained in journalism under the initiative to highlight children’s opinions and aspirations in mainstream media.
Another joint initiative by the two organisations is Prism, the world’s first-ever video news service by children.
At the awards-giving ceremony, Minister Inu said children, specially girls, can bring about changes in society if they are allowed to grow up under proper care. "They also should be given the opportunity."
He urged the parents to nurture children's dreams but also teach them to be realistic.
Unicef representative Dzidula Masiku and Chief of Communication, Advocacy and Partnership Section Shima Islam, too, addressed the ceremony.
