In this November 25, 2017, file photo, a cut Musang King durian is shown by a vendor during the International Durian Cultural Tourism Festival in Bentong, Malaysia. The pungent smell of the rotten durian fruit at the Royal Melbourne Institute of Technology university campus library in Melbourne, Australia, on Saturday, April 28, 2018, was mistaken for a gas leak, prompting an evacuation of the building. Specialist crews wearing masks searched the library, but all they found was rotting durian in a cupboard. About 600 staff and students cleared the building. (Photo by Sadiq Asyraf/AP Photo)

In this Thursday, May 10, 2018 photo, a fruit vendor sits outside his shop in Stepanakert. Since a six-year separatist war ended in 1994, the mountainous region of Nagorno-Karabakh has been controlled by local ethnic Armenian forces backed by Armenia, yet the territory continues to be claimed by neighboring Azerbaijan which has fought all attempts by the self-proclaimed Republic of Artsakh for international recognition. For the fiercely proud people of Nagorno-Karabakh, life in political limbo has meant restrictions on travel, trade, economic development and education opportunities for its youth.
