U.S. patriot missiles in Poland early April: report | Reuters

The Patriots are part of a Polish-U.S. agreement signed last December to upgrade the NATO member's air defenses, following Washington's decision last September to scrap a Bush-era Missile Shield incorporating installations in Poland and the neighboring Czech Republic. Russia has repeatedly warned against stationing NATO missiles in former Soviet-bloc countries and said it would beef up its naval base across the border from Poland in its Baltic enclave Kaliningrad.
