Russia bombs U.S.-backed Syrian rebels near Jordan border

 'Russian warplanes bombed U.S. backed Syrian rebels near the Jordanian border, Pentagon officials say, causing the U.S. to divert armed aircraft to the scene of the strike.

 The strikes, which the U.S. says killed some New Syrian Army troops, occurred about six miles from the Jordanian border, according to a U.S. defense official. The U.S. diverted armed FA-18s to the area after the first round of two strikes, and the pilots then tried to call the Russians on a previously agreed-upon pilot-to-pilot communications channel but did not receive an answer.

 As soon as the U.S. jets left the area to refuel, the Russians came back for another round of bombing, the defense official said.

 "Russia's latest actions raise serious concern about Russian intentions. We will seek an explanation from Russia on why it took this action and assurances this will not happen again." '
