KIEV (Reuters) - Ukrainian President Petro Poroshenko signed a new military doctrine on Thursday naming Russia as the main military threat to Ukraine, according to a statement on the presidential website.

Ukraine and NATO accuse Russia of providing pro-Russian separatists with arms and troops in support of a rebellion in which nearly 8,000 have been killed since it broke out in eastern regions in the spring of 2014, after the fall of Kiev's pro-Moscow president to a popular uprising.
