"The Defense Department and State Department have notified Congress of our intent to use $19 million in global security contingency fund authority to train and equip four companies and one tactical headquarters of the Ukrainian national guard as part of their efforts to build their capacity for internal defense," Pentagon spokesman Rear Admiral John Kirby told reporters.

The training, which requires congressional approval, would occur at a location within Ukraine that hosts multilateral exercises, Kirby said.

The trainers would be provided by U.S. Army Europe and by the California National Guard, he added.

While Kirby did not link the training to the West's deepening standoff with Russia over Ukraine.

The announcement comes as the United States and other Western nations seek to tighten pressure on Moscow after the July 17 downing of a Malaysian airliner over rebel-held territory in Ukraine by what Western nations claimed was a Russia-supplied missile. However Moscow strongly rejected the allegation.

Earlier on Friday, President Barack Obama urged Russian leader Vladimir Putin to stop supporting separatists in eastern Ukraine and to seek a diplomatic end to the crisis.

Washington and European nations announced new sanctions against Russia earlier this week.

While the United States has repeatedly slammed Russia's troop buildup along the border with Ukraine and its support for the rebels, the Obama administration has officially announced its military interference within Ukrainian internal crisis via providing military training by 2015.

Also on Friday, the United States pledged about $8 million in new aid to bolster the Ukrainian border guard service.
