Cleveland Fire Brigade condemned the shocking attacks after firefighters were targeted at South Bank and Hemlington
A firework hit a firefighter after it was hurled towards him by yobs.
And in another incident a large flaming stick from a bonfire was launched towards crews from Cleveland Fire Brigade.
The shocking incidents forced firefighters to stand down on Bonfire Night, one of their busiest nights of the year.
The first incident happened in Oliver Street, South Bank , when firefighters went to extinguish a large bonfire around 7pm.
The crews were subjected to violence and abuse, with a large ignited stick being thrown in their direction.
Fortunately none of them were injured.
Then, an hour and a half later, in Dallas Court, Hemlington, youths began throwing fireworks at crews, with one of the crackers hitting the watch manager who was in charge of the job.
Again, he thankfully suffered no injuries.
Cleveland Fire Brigade confirmed crews were targeted as they responded to incidents across Middlesbrough.
A spokeswoman for Cleveland Police also confirmed the incidents and that its officers had attended to support their fire brigade colleagues.
In response to the South Bank saga, control room operators received a report at 7.10pm that two fire crews had to stand down after having missiles thrown at them.
"Our officers did attend the scene and searched the area but the youths, believed to be responsible, had left prior to our arrival," she said.
"We obviously takes reports of this nature extremely seriously as the force and the fire service work to protect the public everyday and anyone caught behaving in this way will face the full force of the law."
As for the Hemlington incident, police said there were reports of youths hurling fireworks and glass bottles being thrown on to a fire.
Other people also reported similar issues being thrown at properties in the Brusselton Court area of Parkfield in Stockton .
Steve Johnson, Area Manager Prevention and Protection from Cleveland Fire Brigade said: “We received fewer calls than last November 5 which is positive, however we did have incidents of violence towards our crews and this will not be tolerated.
"We continue to receive a high volume of calls around this period and these small fires are a needless drain on our resources and can take us away from real emergencies where lives may be at risk.
"We appreciate the continued public support in keeping our communities safe."
According to research from the Fire Brigades Union (FBU) there were 1,170 attacks on UK firefighters in the last year.
Matt Wrack, FBU general secretary, said: "The attacks we’ve seen on our hardworking firefighters are absolutely appalling.
"Firefighters put their own lives on the line to save others – they are a vital part of the community and will save anyone and everyone, regardless of who they are, which could even include their attackers.
“This Bonfire Night has seen attacks on overstretched and under-resourced crews across the country.
"The Tories have cut 11,500 firefighters since 2010; the last thing these crews need is to be attacked on one of their busiest nights of the year.”
People can reported attacks on fire crews to police on 101 or confidentially to Crimestoppers on 0800 555111.
