US-style "supermax" jails could be built to house the most dangerous offenders following a spate of alleged attacks on staff, the prisons minister has said.
James Timpson told the Politics Hub with Sophy Ridge that "we shouldn't rule anything out" when asked if the most dangerous criminals should be placed in top security prisons.
It comes after Southport triple killer Axel Rudakubana allegedly threw boiling water from a kettle at an officer at HMP Belmarsh on Thursday. Police are now investigating.

Before that, three prison officers were also allegedly attacked by 28-year-old Hashem Abedi - the brother of Manchester Arena bomber Salman Abedi - with hot cooking oil and "improvised knives", potentially made from a baking tray.
Speaking from HMP Preston for a special programme of the Politics Hub, Mr Timpson told Sophy Ridge: "We inherited a complete mess in the prison system.
"Violence is up, assaults on staff is up. But for me, we shouldn't rule anything out."
He added: "What we need to do is to speak to our staff. They're the experts at dealing with these offenders day in, day out. "
Mr Timpson - who was the chief executive of Timpson Group before he was appointed prisons minister last year - said the violence in prisons was "too high".
He continued: "The number of people when you have prisons are so full, and the people in there are not going to education or into purposeful activity.
"You get more violence and that is totally unacceptable. Our staff turn up to work to help turn people.
"They want to turn people's lives around. They didn't turn up to work to get assaulted. It's totally unacceptable."

Reflecting on the crisis facing the UK prison system ahead of the government's sentencing review, Mr Timpson said a major problem was the high rate of reoffending, saying "80% of offending is reoffending".
He said people were leaving places like HMP Preston "addicted to drugs, nowhere to live, mental health problems - and that's why they keep coming back".
Asked whether every prison had a drugs issue, he replied: "100%."
"If we want to keep the public safe, we need to do a lot more of the work in here and in the community. But also we need to build more prisons."
Put to him that making more use of community sentences - thought to be one of the recommendations in the government's sentencing review - might be considered a "cushy option" compared to a custodial sentence, Mr Timpson said: "There are some people in this prison tonight who would prefer to be in prison than do a community sentence - but that's not everybody.
"Community sentences need to be tough punishments outside of prison, not just to help them address their offending behaviour, but also the victims need to see punishments being done too and for me, technology has a big part to play in the future."
