WARSAW (Reuters) - Two advanced U.S. F-22 fighter jets arrived in Poland on Monday for a one-day working visit, the Polish army said, a part of Washington's efforts to reassure allies made uneasy by Russian actions in Ukraine.

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.
