Puri, who has been elected for a two-year term, replaced the ambassador and the permanent representative of Turkey, Ertugrul Apakan.
Earlier Puri stated, "One of our major pre-occupation is the issue of terrorism. I expect that in the coming months we would have to address that issue through the work of the Council."
