Six customers at the Brown Hare pub in Harehills Lane, Leeds, were injured when a man threw a commercial firework into the bar at 6.50pm on Saturday. Police said the firework produced more than 150 separate explosions, causing extensive damage but no serious injuries.
And in York the firework display – intended as one of the highlights of the 400th anniversary of the Gun Powder Plot by one of its most notorious sons – came in for criticism.
Green councillor Andy D'Agorne claimed the site chosen to set off the fireworks at Museum Gardens meant many thousands of people who had assembled near the Minster could not see the display clearly.
Hundreds of onlookers flooded onto Lendal and Ouse Bridges, bringing traffic to a halt and Coun D'Agorne said: "It was potentially dangerous, with families with small children jammed close to crowds surrounding cars and a bus stuck on Lendal Bridge."
The Humberside service was the busiest, with more than 400 calls and attacks on fire fighters, mainly in Grimsby but also right across Hull as hordes of youths turned on the 999 staff.
In one incident in Grimsby, a team was prevented from dealing with a blazing car when they were pelted with fireworks.
In other incidents, Humberside Fire and Rescue group manager Nick Grainger said objects were hurled at both the firefighters and engines.
"That occurred right across the service area so that does concern us," he said.
"If you set a bonfire supervised by a responsible adult in a safe position we will not attend. We are not out to spoil anyone's fun. But these were bonfires in illegal areas with hordes of youths around them."
There were also a number of pranks involving fireworks despite earlier warnings by Humberside Police that they would be dealt with severely using new powers.
In Hull a firework was dropped into a post box, starting a blaze. In Beverley, a firework was pushed through the letter box of a house and exploded in the box, causing damage.
North Yorkshire Fire and Rescue Service dealt with 42 bonfire-related incidents, including damage to two house roofs. The worst was at Harwood Dale, west of Scarborough,when a fire was discovered in the roof of a detached cottage.
Firefighters were unable to prevent damage to external and internal timbers and there was also some damage to a bathroom. The fire is believed to have been caused by a rocket.
Earlier, they were called to Northcliffe Avenue in Scarborough where a firework had become wedged in the eaves of a house causing smoke damage.
At an organised bonfire at Reeth in Swaledale firefighters gave first aid to a woman who got sparks in her eye.
West Yorkshire Fire Service received more than 350 calls between 6pm and 11.30pm, many to bonfires, while a West Yorkshire Ambulance Service spokesman said it was "an extremely busy night".
