The Islamic State in Iraq and Syria (ISIS) is claiming responsibility for Tuesday's deadly attacks in Brussels, The Washington Post reported.
ISIS fighters "carried out a series of bombings with explosive belts and devices," according to the Amaq News Agency, an organization closely associated with the terror group.
The Amaq report added that ISIS fighters opened fire in the Zaventem airport as well.
The coordinated attacks came on the heels of similarly coordinated attacks in Paris in November, which left 130 dead and hundreds more injured. ISIS claimed responsibility for those attacks as well.
Much of the carnage in that attack came at the Bataclan theatre in Paris, where 89 people were killed amid a hostage situation and standoff with authorities.
The Brussels attacks are likely to stoke further scrutiny of U.S.-led efforts to push back against ISIS, including pressure on authorities in Europe to tighten security efforts to prevent such attacks.
Republican presidential candidates on Tuesday criticized the Obama administration's strategy to defeat the terror group.
