TWITTER users have been reporting hearing the boom or seeing a light in the sky last night.

But Rhiannon Powell missed it. She joked: "Am I the only one in Cwmbran who didn’t hear the loud bang? I can, However, confirm that it wasn’t a meteor but an alien spaceship."

@RhiannonKPowell: The people of Cwmbran are being rounded up as I type!! #aliensincwmbran @garyleck17: @cwmbrantweets Is it true Cwmbran is being bombed?

@emilugh: What the hell just went on in Cwmbran??? The massive bang that everyone seems to have heard? #ohgod

 

@FutbalFox: Explosion/alien invasion/riot/fire/lightning in Cwmbran. #PrayForCwmbran @Jordlol: Seriously though, It must have been a huge bang in Cwmbran if I heard it in Blaenavon.
