MOSCOW: The Kremlin said on Tuesday that so far there were no indications that the United States' involvement in the Middle East conflict would affect the pace of the peace talks on Ukraine, but added that "time will tell" given how much attention Washington was having to give the situation.

Kremlin spokesman Dmitry Peskov said it was clear that the U.S. had more work to do in the Middle East, and that it was difficult to discuss a possible next meeting with Ukrainian and U.S. delegations in Abu Dhabi.
