Aids and HIV charities from across the world have been paying tribute to world-renowned AIDS researcher Joep Lange, who died after a Malaysia Airlines flight crashed over Ukraine, killing 298 people.
Lange was due to attend the International AIDS Conference underway in Melbourne, along with numerous other attendees on board, the organisers said.
Earlier, the conference organisers said:
At this incredibly sad and sensitive time the IAS stands with out international family and sends condolences to the loved ones of those who have been lost to this tragedy.
The IAS is hearing unconfirmed reports that some of our friends and colleagues were on board the flight and if this is the case this is a truly sad day.
The IAS has also heard reports that among the passengers was a former IAS President Joep Lange and if that is the case then the HIV/AIDS movement has truly lost a giant.
Thousands of online users have taken to social media to call for the victims of the Malaysian airliner crash to be returned to loved ones.
United States intelligence officials admitted that they do not know who fired the surface-to-air missile that downed flight MH17.
