U.S. President Barack Obama says he has offered the prime minister of Belgium the "full array" of U.S. support in bringing to justice any terrorists involved in planning or aiding in the "unconscionable attack on innocent men, women and children" in Brussels this past week.
In his weekly Saturday address, Obama said Belgium is a close friend and ally of the U.S. and "when it comes to our friends, America has their back, especially as we fight the scourge of terrorism."
A team of agents from the Federal Bureau of Investigation is already in Belgium supporting the investigation into the terrorist attack, according to the president.

"We're going to continue to root out and defeat ISIL," he said. "We've been taking out ISIL leadership and this week, we removed one of their top leaders from the battlefield - permanently."
President Obama said this coming week when dozens of world leaders come to Washington for a nuclear security summit "We will use that opportunity to also review our joint efforts against ISIL and to make sure the world remains united in this effort to protect our people."
