Previous to 2022, this on-line newspaper additionally used one other area, hunzanews.com, as indicated within the web page transparency data on the location’s Fb web page (see Determine 2) and the Web Archive information of hunzanews.com, Web Archive knowledge additionally exhibits that hunzanews.com had been delivering information since 2013; due to this fact, for round 5 years, this on-line newspaper was publishing articles through two web sites: hunzanews.internet and hunzanews.com.
