Obama Pledges U.S. Support To Belgium After Attacks

President Barack Obama pledged to "do whatever is necessary" to help Belgian authorities seek justice for the more than two dozen people who were killed Tuesday in explosions at the Brussels airport and the subway system.

"We stand in solidarity with them in condemning these outrageous attacks against innocent people," Obama said in Havana, where he was closing a historic three-day visit. He commented on the events in Brussels at the top of a keynote address to the Cuban people.

"We will do whatever is necessary to support our friend and ally Belgium in bringing to justice those who are responsible," Obama said. He said America's thoughts and prayers are with the people of Belgium.

Obama said Tuesday's attacks provided yet another reminder "that the world must unite," regardless of nationality, race or faith in "fighting against the scourge of terrorism."

"We can and we will defeat those who threaten the safety and security of people all around the world," he said.

Obama was briefed earlier Tuesday on the attacks. He also telephoned Prime Minister Charles Michel to offer condolences.
