The US will take a decision soon to store heavy weapons including tanks and infantry fighting vehicles in Poland, the Polish defence minister says.
Tomasz Siemoniak said he had discussed such US military deployments last month with US Defence Secretary Ash Carter.
The US military has been conducting massive drills with Nato allies in Eastern Europe amid regional alarm over Russia’s role in the Ukraine conflict.
Russian officials said the plan could have “dangerous consequences”.
The three Baltic states also plan to store US heavy weapons, officials say.
The US has confirmed only that it is to send an armoured brigade of up to 250 vehicles, including tanks, to Germany to support its Nato allies.
US Defence Secretary Ashton Carter will decide in due course whether any of those vehicles will be deployed to other European countries.
