U.S.-led coalition against Islamic State forces gaining momentum IS 격퇴를 위한 미국

Federal authorities in the U.S. say they have identified the masked killer shown beheading Western hostages in a series of videos released by Islamic State. With more, we turn to Paul Yi at the News Center. Paul, the U.S. has been putting the pressure on this extremist group on all fronts,... from political to military action. And it looks like they′ve now "got their sights" on this so-called... I-S propaganda spokesman. Right, Washington is using every means at their disposable to degrade and eventually wipe out this terrorist organization... and that includes the FBI. The bureau stopped short of revealing the full identity of the masked I-S militant, who is believed to be from Britain. This as the Pentagon said the the fight against the jihadists in Iraq and Syria... is only just beginning. Our Kim Ji-yeon reports. The U.S.-led coalition fighting Islamic State militants in Iraq and Syria is making some progress. During a briefing with reporters in Washington, FBI Director James Comey said the U.S. has determined the identity of the militant who beheaded two American journalists and a British aid worker in Syria... but he would not be drawn on releasing his name to the media. The video-taped beheadings of Americans James Foley and Steven Sotloff were major factors in U.S. President Barack Obama′s decision to strike IS militarily... with the group′s main strongholds in Syria the main targets of U.S. airstrikes this week. The Pentagon on Thursday released a video of its airstrikes against the Mayading Modul Refinery, a target that′s under IS control in eastern Syria. Attacks on oil refineries are intended to undermine the group′s ability to finance itself from oil sales. The U.S.-led coalition to fight the extremist group is gaining momentum as Britain announced on Thursday that it would join. Prime Minister David Cameron is waiting for parliament to grant its official approval. Other Western allies of the U.S. including Australia, Belgium and the Netherlands have agreed to join the airstrikes in Iraq. Despite these developments, the Pentagon says it′s too early to say whether the U.S.-led coalition is "winning" against IS. A spokesperson pointed to Islamic State′s continued access to financing, volunteers and weapons... even after the aerial bombing campaign against them began last month. Kim Ji-yeon, Arirang News.
