Muazzem Ali, also a freedom fighter, was given state guard of honour at state guesthouse Padma on after his first namaj-e-janaza earlier in the day.
His second namaj-e-janaza was held at Gulshan Azad Mosque after Zuhr prayers. He was then laid to rest at Banani graveyard.
His qulkhawani will be held on Friday, said an official.
Representatives of President Abdul Hamid and Prime Minister Sheikh Hasina placed wreaths on his coffin at State guesthouse Padma.
Foreign Minister Dr AK Abdul Momen, State Minister for Foreign Affairs M Shahriar Alam, former Finance Minister AMA Muhith, former Foreign Minister AH Mahmood Ali, newly-appointed Foreign Secretary Masud Bin Momen, Dean of Diplomatic Corps and Ambassador of the Vatican to Bangladesh Archbishop George Kocherry, Indian High Commissioner in Dhaka Riva Ganguly Das, former diplomats and senior officials at the Ministry of Foreign Affairs were present there to show their last respects to late Muazzem Ali.
Members of Diplomatic Correspondents Association, Bangladesh (DCAB) also paid their last respects to the diplomat.
Dr Momen, who had close family ties with Muazzem Ali, described him as “a very capable diplomat” who had a “very high acceptability”.
“He’s always been a fully committed person and a good soul,” Momen told reporters at the State guesthouse Padma after the first namaj-e-janaza. “I feel so bad.”
The nation will always remember him for his contributions during the War of Liberation in 1971, said the Foreign Minister.
In Paris, Dr Momen recalled, Muazzem Ali was also Bangladesh’s Permanent Representative to UNESCO. In that capacity, he tabled a draft resolution on behalf of Bangladesh for the proclamation of February 21 as the International Mother Language Day.
He spearheaded the lobbying efforts and its unanimous adoption by the UNESCO General Conference in 1999.
Syed Muazzem Ali, 75, passed away on Monday at the Combined Military Hospital (CMH) in the capital while undergoing treatment days after he returned from New Delhi following his five-year stint in India.
