US Republican presidential nominee Donald Trump has responded to accusations by the father of a slain Muslim soldier that he has "sacrificed nothing" by claiming he has "made a lot of sacrifices".
The billionaire businessman was responding to comments by Khizr Khan, whose son, a US Muslim soldier, was killed in Iraq.
Captain Humayun Khan died in 2004 while trying to stop a suicide bomber outside his camp in Baquba, north-east of Baghdad.
Mr Khan had accused the billionaire of vilifying American Muslims, in a steely rebuke that electrified the Democratic convention on Thursday.
"Go look at the graves of brave patriots who died defending the United States of America," Mr Khan said, directly addressing Mr Trump. "You will see all faiths, genders and ethnicities. You have sacrificed nothing and no one."
In response, Mr Trump pointed to what he said was his strong work ethic and "tremendous success", while taking a jab at Mr Khan's wife.
Mr Trump, who has called for a ban on Muslims entering the United States, told ABC News America that he thought he had made "a lot of sacrifices".
"I work very, very hard. I've created thousands and thousands of jobs, tens of thousands of jobs, built great structures. I've had tremendous success. I think I've done a lot," he said.
He also suggested that Democratic candidate Hillary Clinton's speechwriters had penned Mr Khan's address, which Mr Khan said he wrote with his wife.
"Who wrote that? Did Hillary's script writers write it?" Mr Trump said.
"If you look at his wife, she was standing there. She had nothing to say," he said, adding that "maybe she wasn't allowed to have anything to say".
Mother had spoken earlier about 'hero' son
Earlier, Mr Khan and his wife Ghazala had given a joint interview with MSNBC's Last Word, where they Ms Khan said she had asked her son to be safe and not to "do something stupid" while in Iraq.
"Don't become a hero for me, come back as my son," she said she had asked him.
"He came back a hero," she added.
But Mr Khan explained that a person did not have to wear a uniform to sacrifice.
"Sacrifice includes not threatening others, not making others feel less," he said.
"Sacrifice includes considering the rest of your patriot citizens equal, same, [and] not causing them to worry about their existence [and] their being in the United States".
had elaborated on comments made in Mr Khan's speech.
Clinton says Khan family shows 'the best of America'
In a statement posted on Twitter, Mrs Clinton defended Ms Khan and described the family as "the best of America".
"I was very moved to see Ghazala Khan stand bravely and with dignity in support of her son on Thursday night," she said.
"This is a time to honour the sacrifice of Captain Khan and all the fallen. Captain Khan and his family represent the best of America, and we salute them."
Mr Trump was a punching bag at the Democratic National Convention in Philadelphia, which wrapped up on Friday, as speaker after speaker — including some Republicans — said he lacked the temperament to be president.
The roasting led Mr Trump to declare there would be "no more Mr Nice Guy" from him in the race for the White House.
