Crews were called to reports of a fire in Pwllheli at around 10:20pm on Friday, with two wildfire vehicles and two fire engines remaining at the scene on Saturday afternoon.

No one was injured and there was no wider risk to people in the local area, NWFRS said.
A spokesperson for North Wales Fire and Rescue Service said: "We arrived at the scene of the fire on Pen Garn at 10:20pm."Firefighting is still in operation at this time."
