Washington D.C. - U. S. Senator Pat Toomey (R-Pa.) released the below statement following the terrorist attack at the Brussels airport:

"My sympathies and condolences go out to those killed and wounded by the deadly terrorist attacks in Brussels, including some Americans. My thoughts are also with their families and the first responders. Belgium is a close ally, and we stand shoulder to shoulder with the Belgian people in the face of such violence.

"Sadly, Brussels now joins Paris, San Bernardino, Beirut, Istanbul, and other cities as backdrops for mass killings by Islamist extremist terrorists within the past year. Only a couple months ago, one such terrorist tried to kill a police officer in Philadelphia.

"Today is another reminder about the threats we face from terrorism. Clearly, it remains a serious security risk. We must remain vigilant and step up our efforts to protect the American people and our allies."
