Northern Ireland Fire and Rescue Service (NIFRS) received 303 emergency calls, and responded to 151 operational incidents, between 18:00 BST on Saturday and 02:00 on Sunday.
Some bonfires across Northern Ireland were lit ahead of the Orange Order’s Twelfth of July parades.
Fifty four of the emergency calls were bonfire-related, and in Cookstown, County Tyrone, firefighters had to withdraw from a bonfire due to a “hostile crowd”, NIFRS said.
In a separate incident in Greenisland, Carrickfergus, the fire service dealt with a row of terraced houses, along with two oil tanks and a shed, on fire. Two homes were completely destroyed with damage caused to a further two properties.
The cause of the fire is under investigation.
