George Zimmerman, the neighbourhood watch volunteer who shot dead an unarmed black teenager in a case that reignited racial tensions in America, has described the incident as "God's plan".
Mr Zimmerman is charged with murder after shooting 17-year-old Trayvon Martin in Sanford, Florida, in February. He admits killing Trayvon but says he fired in self-defence.
Fox News broadcast an interview with the 28 year-old this week in which he was asked if he regretted leaving his vehicle on the evening in question or regretted carrying a gun. "No Sir, I feel that it was all God's plan," he said.I simply really don't know what God George Zimmerman is worshipping because there's no way that the God that I serve had in his plans for George Zimmerman to murder my son.
Mr Zimmerman once again apologised to Trayvon's parents and said he prayed for them every day. But his comments about God's plan drew an angry response from the couple.
"I simply really don't know what God George Zimmerman is worshipping because there's no way that the God that I serve had in his plans for George Zimmerman to murder my son," said Trayvon's father, Tracy.
His mother, Sybrina Fulton, said: "I have a hard time accepting it because he also said that he doesn't regret anything that he did that night, and I don't think God would have him in his plan to murder an innocent child."
Mr Zimmerman gave an account of the evening he shot Trayvon. He said that he was going to buy food when he saw Trayvon skipping between houses in the complex. He said he followed Trayvon and the pair came face to face.
Mr Zimmerman says Trayvon asked him what his problem was before punching him in the face. He says a scuffle ensued, leaving Mr Zimmerman pinned under Trayvon on the floor.
Mr Zimmerman's gun, which was in a holster at his side, became exposed and he claimed that Trayvon saw it and said: "You're gonna die tonight."
Asked about the moment he reached for his weapon, Mr Zimmerman said he first felt Trayvon's hand reach for the gun. "That's when I didn't have any more time," he added.
Later in the interview, after initially saying he had no regrets, Mr Zimmerman asked to readdress the question and added: "I do wish that there was something, anything, I could have done that wouldn't have put me into the position where I had to take his life."
Asked if he had a message for Trayvon's parents, Mr Zimmerman said: "I am sorry that they buried their child. I can't imagine what it must feel like, and I pray for them daily."
Trayvon was shot dead on February 26. Mr Zimmerman, a neighbourhood watch volunteer, was not arrested for weeks after local police initially decided against pressing charges, which led to a storm of protests from the black community.
Asked during Wednesday's interview about a possible racial motivation behind the shooting, Mr Zimmerman said: "I'm not a racist, and I'm not a murderer."
As the interview ended, he acknowledged the impact the killing of Trayvon had on US society. The case drew comment from President Barack Obama, who called the case a "tragedy" and said that if he had a son he would look like Trayvon.
Looking directly into the camera, Mr Zimmerman said: "I do want to tell every-one, my wife, my family, my parents, my grandmother, the Martins, the city of Sanford and America that I'm sorry that this happened.
"I hate to think that because of this incident, because of my actions, it's polarised and divided America. And I'm truly sorry."
After his arrest in April, Mr Zimmerman was charged with second degree murder and spent time in prison before being released on $US1 million bail.
He has pleaded not guilty and his attorney said his trial could be more than a year away.
