Prime Minister Sheikh Hasina has joined other world leaders in mourning the death of Prince Philip, husband of Britain's Queen Elizabeth II.
Prince Philip died on Friday at Windsor Castle at the age of 99, reports bdnews24.com.
Hasina wished peace for the departed soul and conveyed deep sympathy to the members of the bereaved royal family, the Prime Minister's Office said in a statement on Friday.
The Duke of Edinburgh, as he was officially known, had been by his wife's side throughout her 69-year reign, the longest in British history.
"It is with deep sorrow that Her Majesty The Queen announces the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh," the palace said in a statement.
"His Royal Highness passed away peacefully this morning at Windsor Castle. Further announcements will be made in due course. The Royal Family join with people around the world in mourning his loss."
Britain's Prince Philip has died
Flags at Buckingham Palace and at government buildings across Britain were lowered to half-mast and within an hour of the announcement the public began to lay flowers outside Windsor Castle and Buckingham Palace.
The royal family's website was also shut down, replaced by a photo of Philip and the announcement of his death.
A Greek prince, Philip married Elizabeth in 1947. He went on to play a key role helping the monarchy to adapt to a changing world in the post-World War Two period, and behind the walls of Buckingham Palace was the queen's closest confidant.
Philip spent four weeks in hospital earlier this year for treatment for an infection and to have a heart procedure, but returned to Windsor in early March. He died just two months before his 100th birthday.
