Ukraine will get night-vision goggles and unmanned aerial vehicles as part of the U.S. assistance this week, U.S. Ambassador to Ukraine Geoffrey Pyatt said. Speaking at a meeting of the "Open World" discussion club in Kiev on Tuesday, Pyatt said that the U.S. has pledged more than $600 million in assistance in the field of security. Another delivery of drones will take place this week, while more night vision devices will be delivered in the next few days, he said.
