Talking about the attacks Ronan explained:
"You can't breathe, you feel like your chest is collapsing, the walls are coming in on top of you.
"My brain doesn't work. My heart's broken. You just feel crushed. It's been horrible. We've all been feeling the same way since Stephen passed. Mentally I'm absolutely exhausted."
Keating admits that after losing Stephen at such a young age (33), he’s understandably been questioning his faith.
"I've had moments where I've questioned. I didn't understand. I don't understand. I'm angry. I'm upset. My friend's gone."
Meanwhile the Boyzone star has a new solo album out tomorrow called Winter, and we caught up with him performing a few tracks from the new project last night in Düsseldorf in Germany at the UNESCO Charity Gala, where we also spotted Jermaine Jackson and Forrest Whitaker.
