Embassy of Bosnia and Herzegovina in India
embassy · New Delhi, India
Wikipedia lists New Delhi as the accrediting seat, and a UNB report says the New Delhi embassy ran a consular camp in Dhaka for visas. Directories disagree on the address (E-8/5 vs E-9/11 Vasant Vihar) and the only email is a Gmail address, so address/phone/email left null pending confirmation from the Ministry of Foreign Affairs of BiH.
