A man has been found guilty of murdering his ex-partner's sister and her three children in a house fire.
Prosecutors said Sharaz Ali, 40, was "motivated by jealousy and fuelled by drink and drugs" when he set fire to Bryonie Gawith's home early on 21 August last year.
Jurors heard that Ali went to the home in Westbury Road, Bradford, aiming to "take revenge" on his ex, Antonia Gawith, who was staying there after ending their "abusive" seven-year relationship earlier that month.
Antonia Gawith managed to escape, but Bryonie Gawith, 29, and her children Denisty Birtle, nine, Oscar Birtle, five, and 22-month-old Aubree Birtle died in the blaze.
Ali told a jury he had no intention of harming others when the house went up in flames, saying: "I didn't want to hurt anyone but myself."
But after a trial at Doncaster Crown Court, he was found guilty of four counts of murder and attempting to murder Antonia Gawith.
Calum Sunderland, 26, who went with Ali to the house and kicked the door in for him, was found guilty of the manslaughter of Bryonie Gawith and her three children, but cleared of the more serious charges of murder.
He was also cleared of attempted murder, and an alternative count of attempting to cause grievous bodily harm, in relation to Antonia Gawith.
Mohammed Shabir, 45, who had also been due to go on trial, died of a heart attack in October after collapsing in prison.
Reading a statement on behalf of her family outside court, Antonia Gawith said her sister, nieces and nephew's futures have been "stolen".
"Even with justice, nothing will ever make this right," she said.
"Nothing will ever fill the silence where their laughter should be. Nothing will ever bring back our family.
"We will forever carry this brokenness, and yet we will hold on to them tightly in only ways we can now, through our memories, our photos and our precious videos. Those are all we have left now."
After the verdicts, the judge, Mr Justice Hilliard, thanked jurors and said the case had been "distressing beyond measure - three children and their mother murdered".
"I don't think anyone who heard Antonia's desperate cries for help will ever forget them," he said.
"These are truly dreadful crimes."
The judge also praised the "extraordinary bravery" of those who tried to save the children trapped in the house.
Ali and Sunderland, a convicted arsonist, were driven to the house by Shabir, stopping on the way to fill a seven-litre canister with petrol, the court heard.
Doorbell footage captured Ali telling Sunderland, who was carrying the petrol and a lighter, to "kick the door in", which he did before running back to the car.
Antonia Gawith said she saw an "angry" Ali run into the house and begin pouring petrol on her while shouting before setting himself and the house on fire.
'I couldn't save them'
In a video interview played to jurors, she sobbed as she told police how she "couldn't save" her sister, nieces and nephew, as she tried frantically to get back in the house through the back door.
"I was just screaming, trying to get back in the house and I couldn't get in. I couldn't save them," she said.

West Yorkshire Police's Detective Chief Inspector Stacey Atkinson said: "Bryonie and her three children would still be alive today if it wasn't for the horrific and truly callous actions of Ali and Sunderland that day.
"They left a mum and her three children completely helpless whilst her sister and their auntie watched on in horror.
"Our thoughts and sympathies are with the family, who despite their immense strength of character now face the rest of their lives without them."

Senior Crown Prosecution Service prosecutor Amanda McInnes said Ali was a "selfish killer who had no regard for anyone but himself".
"He was motivated by jealousy and his actions have now needlessly robbed a family of their loved ones," she said.
"Both men played their role and caused the deaths of a young family who should still be with us today."
