U.S. Broadens Fight Against ISIS With Attacks in Afghanistan

WASHINGTON — The United States has carried out at least a dozen operations — including commando raids and airstrikes — in the past three weeks against militants in Afghanistan aligned with the Islamic State, expanding the Obama administration’s military campaign against the terrorist group beyond Iraq and Syria.

The operations followed President Obama’s decision last month to broaden the authority of American commanders to attack the Islamic State’s new branch in Afghanistan. The administration — which has been accused by Republicans of not having a strategy to defeat the group — is revamping plans for how it fights the terrorist organization in regions where it has developed affiliates.
