President Obama Grim as He Receives News of Brussels Terror Attacks in White House Photo

— -- In this White House photo, President Barack Obama is grim as he receives an update on this morning's terror attacks in Brussels, Belgium.

The president can be seen listening intently as he puts business on hold while on a historic visit to Cuba. He is flanked by National Security Advisor Susan E. Rice.

The photo was taken at the Havana residence of the U.S. Chief of Mission.

There were two explosions in the departure hall of Brussels Airport in Zaventem, Belgium, at about 8 a.m. local time today, according to Prime Minister Charles Michel, where officials said at least 14 people were killed. Three Americans, Mormon missionaries, were "seriously injured" in the blasts, according to Eric Hawkins, a spokesman for the Church of Jesus Christ of Latter-day Saints.

There was also an explosion a little over an hour later on the rail tracks at the Maelbeek subway station, according to a spokeswoman for Brussels transportation department. At least 20 people were killed there, officials said.

In a statement made earlier this morning, Obama condemned the "outrageous attacks against innocent people," adding that the U.S. will do whatever necessary to aid the Belgium authorities.

“We stand in solidarity with them in condemning these outrageous attacks against innocent people. We will do whatever is necessary to support our ally Belgium in bringing to justice those who are responsible,” Obama said.
