Talks between Kerry and Lavrov

The United States, on the eve of the negotiations, has been deliberately aggravating the situation in Syria, and Ukraine. Ukrainian troops have increased their intensity of the shelling of Donbass after the failure of attempts to organize terrorist attacks in Russian Crimea. Officials of the UN Commission published a report in which it accused the Syrian government of using chemical weapons. This document is now being used to put pressure on Moscow and Damascus. For the US  this is a possible cause for direct intervention in the conflict.
