WARSAW, Dhu-AlQa'dah 16, 1436, Aug 31, 2015, SPA -- Two advanced U.S. F-22 fighter jets arrived in Poland on Monday for a one-day working visit, a part of Washington's efforts to reassure allies made uneasy by Russian actions in Ukraine, Reuters quoted the Polish army as saying. The visit is a part of the F-22's first-ever deployment to Europe, where four of the stealth fighters will train with allied air forces and U.S. services through mid-September. The four aircraft arrived at Spangdahlem Air base in Germany on Friday. "The U.S. is conducting reconnaissance of abilities of operating this type of aircraft at an allied airport," Polish army spokesman Artur Golawski told Reuters. The planes landed at a military air base in Lask, in central Poland. --SPA 13:04 LOCAL TIME 10:04 GMT www.spa.gov.sa/w
