VIENNA/MOSCOW (Reuters) -Poland's foreign minister said on Thursday that Europe was at risk of plunging into war as Russia said it was not yet giving up on diplomacy but that military experts were preparing options in case tensions over Ukraine could not be defused.

In Washington, the White House said the threat of a Russian invasion of Ukraine remained high with some 100,000 Russian troops deployed and the United States would make public within 24 hours intelligence suggesting Russia might seek to invent a pretext to justify one.
