International AIDS Society President Francoise Barre-Sinousi said that at least six delegates heading to attend a global AIDS conference here were killed in the Malaysian plane crash in eastern Ukraine. Barre-Sinoussi said that Joep lange, former president of the International AIDS Society and a well-known HIV researcher from the Netherlands, was also killed in the crash. She also said six delegates were on board and two more delegates may have been on the flight. “The number that we have confirmed through our contacts with authorities in Australia, in Malaysia, and Dutch authorities as well is six people. It may be a little bit more, but not the numbers that have been announced,” she said. According to media reports yesterday, at least 100 top researchers and participants were on board the flight which was brought down in eastern Ukraine by a surface-to-air missile on Thursday.
