The Wall Street Journal reports,"Ukraine's interim government has appealed for U.S. military aid, including arms, ammunition and intelligence support, according to senior U.S. officials. But the Obama administration has agreed to send only military rations for now, wary of inflaming tensions with Russia.
The U.S. decision reflects the Pentagon's reluctance to be seen as directly supporting Ukraine's beleaguered armed forces during the standoff with Russia, which has seized the Ukrainian region of Crimea.
The risk of escalation was underscored by Russia's move on Thursday to conduct another military exercise near Ukraine. The Kremlin also confirmed it has sent six Sukhoi fighter jets and three transport planes to another former Soviet republic, Belarus, for joint patrols.
Belarusian officials said the move came in response to increased air patrols in the region by the North Atlantic Treaty Organization amid the Ukraine crisis".
