The brother of Woolwich killer Michael Adebolajo has refused to condemn the murder of Lee Rigby.
Jeremiah Adebolajo told Sky News: "My brother's blood is no more expensive than the blood of an Afghan child, and I think Lee Rigby's blood is no more expensive than an Iraqi child."
When asked if he had any regrets over the murder in Woolwich, Mr Adebolajo replied: "My main regret is that foreign troops are in the land of the Muslims."
Like his brother, Mr Adebolajo believes the foreign policies of the UK and US justify direct action against British soldiers, who they believe are "enemy combatants".
The brothers grew up in Romford, Essex, with their parents and sisters.
Mr Adebolajo said: "We had a fairly ordinary upbringing. We grew up as any other Nigerian young men do I guess in east London, nothing extraordinary.
"My parents were protestant Christians. As you can imagine with most African parents, they consider religion to be something of great importance and we were no different."
Of his brother he said: "He was always concerned I guess with morality. He was a happy guy, he's a bit of a joker.
"A very athletic individual. He loves sports, football. He is an Arsenal fan."
Michael Adebolajo converted to Islam in his first year at the University of Greenwich, his brother said.
His brother said: "I don't think that there was a particular moment when he said 'I have become a Muslim'.
"It was a gradual change we saw in him in which he became more devoted, more practising."
Michael Adebolajo started joining street protests. In 2006 he was arrested and jailed for 51 days for assaulting two police officers when a demonstration turned violent outside the Old Bailey.
His brother, who also converted, rejects the assumption that Adebolajo was radicalised by prominent figures such as Anjem Choudray.
Jeremiah Adebolajo said: "The media have taken this line that we have a disenfranchised young Christian boy who was radicalised by these bogeymen figures, Anjem Choudary, Omar Bakri, it is a simplistic narrative.
"The truth is they had no ideological influence over my brother, none at all."
In 2010, Michael Adebolajo left his family in London and travelled to Kenya hoping to get into Somalia.
It is widely reported he was trying to join al Shabaab but was intercepted by the Kenyan military and then deported back to the UK.
The British security services had a hand in his repatriation to Britain and were trying to recruit Adebolajo to work with them.
His brother said: "I think the public have a right to ask the security services why they brought him back when he wanted to live there under Islamic law."
Jeremiah Adebolajo also now lives abroad working as an English teacher at a university in Saudi Arabia, but has returned to London for the trial at the Old Bailey.
He has visited his brother inside HMP Belmarsh several times, most recently last Saturday.
Mr Adebolajo claimed that Michael was attacked by prison officers who knocked out the killer's front teeth during his time in prison.
He said: "It was five guys who attacked him. One of the reasons he doesn't want to get them (his teeth) fixed is because he doesn't want to hide it.
"My brother is the kind of guy that if we were young we would have a fight, he could get your teeth knocked out so it is not a huge major big deal."
On Thursday, the union for prison workers, POA , said in a statement that all five officers had been exonerated with the Crown Prosecution Service deciding there was no case to answer.
When challenged about the murder of Lee Rigby, Mr Adebolajo said he understood the condemnation of the public but added "we have to think about the reasons for these actions".
He said: "The young lady in Afghanistan who was raped and killed and burned alive by American soldiers, do you think her parents felt something similar to the parents of Lee Rigby?
"There is a danger in dehumanising Afghanistanis.
"My brother is under no illusion that his actions are going to have an overarching effect on foreign policy. He considers himself a soldier."
