"The news comes as the eurozone's three-year debt crisis continues to make the region a major focus of concern for the world economy."
The b is silent in the word debt. However, while I was listening to this video, neither b nor t was pronounced. There were ignored. I think it is difficult to pronounce t sound in the word debt when it is followed by k sound in the word crisis during connected speech. If I am not mistaken, it has been pronounced as /ˌdiː ˈkraɪ.sɪs/.
I can hear it too.
