根据路透社消息：

Russian President Vladimir Putin ordered the deployment of troops to two breakaway regions in eastern Ukraine after recognising them as independent on Monday, accelerating a crisis the West fears could unleash a major war.

俄罗斯总统普京(Vladimir Putin)周一承认乌克兰东部两个分离地区独立后，下令向这两个地区部署军队。此举加剧了一场危机，西方国家担心这场危机可能引发一场大规模战争。

A Reuters witness saw unusually large columns of military hardware moving through the breakaway city of Donetsk after Putin told Russia's defence ministry to send forces into the two regions to "keep the peace" in a decree issued shortly after announcing recognition for Russian-backed separatists there.

一名路透社目击者看到，在普京宣布承认俄罗斯支持的顿涅茨克分裂分子后不久，俄罗斯国防部发布命令，要求俄罗斯向这两个地区派遣部队，以“维护和平”，随后，不同寻常的大型军事装备车队在顿涅茨克穿行。

The moves drew U.S. and European condemnation and vows of new sanctions although it was not immediately clear whether the Russian military action would be regarded by the West as the start of a fullscale invasion. The area was already controlled by Russian-backed separatists and Moscow in practice.

此举招致美国和欧洲的谴责，并誓言要实施新的制裁，尽管目前尚不清楚俄罗斯的军事行动是否会被西方视为全面入侵的开始。该地区实际上已经被俄罗斯支持的分裂分子和莫斯科控制。

In a lengthy televised address packed with grievances against the West, Putin, looking visibly angry, described Ukraine as an integral part of Russia's history and said eastern Ukraine was ancient Russian lands and that he was confident the Russian people would support his decision

普京发表了长篇电视讲话，充满了对西方的不满。他看起来很愤怒，称乌克兰是俄罗斯历史不可分割的一部分，并称乌克兰东部是古老的俄罗斯领土，他相信俄罗斯人民会支持他的决定。

Moscow's action may well torpedo a last-minute bid for a summit with U.S. President Joe Biden to prevent Russia from invading Ukraine.

莫斯科的行动很可能会破坏与美国总统拜登举行峰会以阻止俄罗斯入侵乌克兰的最后一刻的努力

在普京周一晚间对俄罗斯人民发表电视讲话时，卢布兑美元跌破80，股市则在夜盘交易中一度重挫18%。当天早些时候，俄罗斯基准股指MOEX收跌11%，创下2014年3月以来的最大跌幅。
