A Cambridge University student has been killed in a terrorist attack in Burkina Faso.
Caius PhD student Tammy Chen and her husband were among 18 people killed in a suspected jihadist attack on a restaurant in the west African nation.
Police say that three or four gunmen drove up to the Aziz Istanbul restaurant in the capital Ouagadougou at around 9pm local time on Sunday and opened fire randomly on diners.
The Cambridge college was flying its flag at half mast today to mark her death.
Tammy, a Canadian, was finishing a PhD in International Development, focusing on poverty, gender and women's empowerment.
Professor Fersht paid tribute to her as "an exceptional woman, very active in the Caius graduate community and passionate about her research and helping people. She had so much to offer the world and it is a tragedy for her to be lost so young."
