"I am profoundly saddened by the innocent lives lost in the horrific ISIS attack at the concert hall in Moscow," bahagi ng X post ng Pangulo.
"My deepest condolences to the families affected by this senseless act of terrorism. We stand united in condemning terrorism in all its forms," aniya.
Naiulat na bigla na lamang sumugod ang grupo ng kalalakihang naka-camouflage, pinagbabaril ang concert hall at pinasabugan pa ng mga granada nitong Biyernes ng gabi.
Nauna nang inako ng ISIS ang pag-atake, gayunman walang mailabas na ebidensyang susuporta sa kanilang pahayag.
