A top Russian diplomat lambasted the U.S. decision to provide Ukraine with lethal weapons including Javelin anti-tank missiles, arguing that the move would only further fuel the conflict in the country's east, per The Associated Press.

Why it matters: Ukraine has long been seeking weapons for its fight against pro-Russian separatists in the eastern part of the country, which has killed more than 10,000 since April 2014, AP reports. Former President Obama was reportedly considering to send lethal weapons to Ukraine. The Trump administration's decision would deepen American involvement and further strains U.S. relations with Russia.
