WASHINGTON, Sept 15 () - The White House said on Tuesday that the United States wants to see Russia take on "more constructive engagement" with the international coalition fighting IS militants in Syria, rather than build up its military presence there, Reuters reported. White House spokesman Josh Earnest said he did not have an update on whether or when President Barack Obama would call Russian President Vladimir Putin about the issue. -- SPA 21:51 LOCAL TIME 18:51 GMT www.spa.gov.sa/w
