Three huge explosions woke most of port Talbot and the surrounding area Friday morning around 3:30am.
The source was Port Talbot's steelworks. Breakfast show presenter Leigh Jones who lives in Aberavon said said "It woke the entire house. The sounds of the explosions were unbelievable. The house shook. We were expecting the worst."
Emergency services say the TATA steelworks explosion was caused by a train carrying molten metal onto the site.
A series of small fires caused by the explosion are now under control, and it is believed two people suffered minor injuries.
Emergency services were first contacted at 3.35am after multiple people reported a series of "massive" bangs which shook homes in Port Talbot, and could be heard from as far away as Bridgend. Some residents reported seeing huge fireballs at the steelworks, while others saw debris falling after the bangs were heard. In unsettling images people could see a mushroom cloud rising from the area after the explosions.
TATA Steel confirmed shortly after 5am that the fires were under control. A spokesman for TATA said it all its staff had been accounted for, and that there were no serious injuries. Two people suffered minor injuries.
