President Obama spent exactly 51 seconds discussing Tuesday's terror attacks in Brussels before pivoting back to his prepared remarks in Cuba.

Obama asked the Havana audience to "please indulge me" before committing that the U.S. "will do whatever is necessary" to support the people of Belgium.

"The thoughts and prayers of the American people are with the people of Belgium and we stand in solidarity with them in condemning these outrageous attacks against innocent people," Obama said. "We will do whatever is necessary to support our friend and ally, Belgium, in bringing to justice to those who are responsible."

He said that the attack "is yet another reminder that the world must unite ... regardless of nationality, or race, or faith in fighting against the scourge of terrorism."

Obama is in Cuba as part of the administration's attempt to ease relations between the country and the U.S.
