Washington, Dhu-AlQa'dah 17, 1435, Sep 12, 2014, SPA -- Retired Marine Corps General John Allen will be President Barack Obama's special envoy for the international coalition against the ISIS, the US State Department says, according to dpa. Allen "will help continue to build, coordinate and sustain a global coalition across multiple lines of efforts to degrade and ultimately destroy" the jihadist group, State Department spokeswoman Marie Harf says. Allen, who led the US and allied military effort in Afghanistan from 2011 to 2013, will report to Secretary of State John Kerry with the goal to "work closely with the Department of Defense to match specific campaign requirements and coalition needs with potential contributors," she says. The appointment is meant to give "high-level diplomatic support" for a "global coalition that delivers tangible results," according to Harf. -- SPA 22:28 LOCAL TIME 19:28 GMT www.spa.gov.sa/1272155
