Brussels Terror Attack -- Injured Basketball Player Speaks ... 'Thought About Wife, Kids'

The basketball player who was seriously injured in the Brussels terror attacks says he was thinking about his wife and kids in the moments after the blast ... and how he NEEDED to live to see them again.

Sebastien Bellin suffered major leg and hip damage in the explosion at the airport -- the photo of the former Oakland University basketball star laying in a pool of his own blood went viral.

Bellin was rushed to a hospital for emergency surgery -- and Thursday morning, he spoke with ABC's David Muir in an extremely emotional interview from his hospital bed in Brussels.

You gotta watch the clip ... Bellin details the moments after the attack and how his family is motivating his recovery.
