Sorrell Leczkowski, a 14-year-old girl from Leeds, is the latest person to be identified as having been killed.

She lived in the Adel area of the city and went to Allerton High School.

Her mother and grandmother are in hospital; her grandmother is critically injured. Her sister, who was at the concert, was not injured.

A consultant from Manchester Royal Infirmary and Children's Hospital has been giving a press conference.

He says when he turned up after the incident was declared "it was already running in a very smooth way with established work flows" and it "filled me with pride".

"The volumes [of casualties] were relatively small but we were seeing people very much more sick than we usually get.

"It had the potential to overwhelm us but the response was amazing."

He adds: "I went home not feeling great on Tuesday morning... It's really hard and we need to be aware of that."

The soldiers are to offer back-up to armed police officers after the Manchester bomb attack.

Imam Monawar Hussain founded the Oxford Foundation, which promotes interfaith dialogue and education, and told BBC Oxford he is regularly asked to talk to young people accessing extremist websites.

He said: “I often get called into schools because young people are accessing material on the internet; they’re getting really wound up.

“What the extremists do is they use violence against Muslims to generate hate towards everyone else.

“We actually sit down and go through why they want to go to Syria or anywhere else, what’s the basis for this, and open up other avenues for them to do good.

“That idealism that young people have can be channeled into a positive outcome, rather than something destructive.”

Organisers of Liverpool Sound City Music Festival say this weekend's event will "go ahead as planned" and "not be defeated by such cowardice".

BBC home affairs correspondent Daniel Sandford says the most telling part of the statement by Greater Manchester's chief constable was this: "This is a network we are investigating."

Police believe "this was not a man acting alone".

The absence of a cordon around around the properties raided by the police so far, of a type that would surround "a place where bombs are made", indicate that police have not yet found a "bomb factory", Daniel adds.

As for next steps, the police will "go through everything and eventually, history says, they find that vital clue that gets them where they want to be".

But he anticipates it's "going to be a long, long, tortuous forensic path" to get there.

Soldiers will help guard Sellafield from this afternoon as some members of the armed police force which usually guard the site are sent to other areas of the country.

Sellafield Limited says the change is not down to any increase in the threat to the nuclear site.

BBC Cumbria's Ben Maeder reports: "The Civil Nuclear Constabulary is the UK's only routinely armed police force, and its job is to protect the country's nuclear sites.

"After the national terror threat level was raised to critical, the CNC offered its officers to help in civilian areas, and so some of its officers from Sellafield have been deployed elsewhere.

"To keep the site's security levels unchanged, soldiers will be coming to Sellafield today to help provide security. Sellafield Limited says the overall protection level for the site will stay the same, and staff going onto the site will not see any changes to their usual access and security checks."

Former deputy prime minister Nick Clegg says the government's anti-terror Prevent programme "is in danger of being treated with widespread suspicion".

Chief Constable Hopkins tells reporters police are carrying out "extensive searches" across Manchester.

"It's very clear this is a network we are investigating," he says.

These words went viral in a Facebook message posted by a Manchester nightclub.

Today's Changing the Guard ceremony at Windsor Castle was cancelled to allow armed officers to be deployed elsewhere, the Ministry of Defence (MoD) has said.

A spokesperson for the MoD told the BBC that this fits with an existing arrangement for times of heightened national security.

They added that the decision will be "reviewed" ahead of each scheduled ceremony.

The next ceremony is due to take place on Friday.

The UK terror threat level has been raised to the highest of "critical" following the Manchester Arena attack. Military personnel are being placed in public locations to support police in protecting the public.

Lord Dannatt was Commander in Chief Land Command at the time of the 7/7 bombings in London. He told the World at One that while the presence of troops "might alarm some people", they should be reassured the authorities are taking the threat "really, really seriously".

Fourteen-year-old Nell Jones was "always smiling, always positive", her school says.

There could be further bombs, warns a former head of the UK National Counter Terrorism Security Office.

Chief Constable Hopkins says: "We made three arrests in connection with the attacks overnight and this afternoon we entered an address in Manchester City Centre using a controlled explosion.

"Officers are currently at the scene but in order to do this safely we briefly had to close a nearby mainline railway, which has now been reopened. Those extensive searches will now continue.

"In total we currently have four people in custody.

"People will have seen a significant increase in the number of armed officers in Greater Manchester. We have been supported by forces in the North West and beyond in order to do this and this all forms part of our tried and tested plan for a major terrorist incident.

"With the threat level being increased to critical you will be aware that military are supporting policing across the country. This is about using the military across sites in London and elsewhere to free up armed police officers to support police forces.

"There are no military personnel patrolling Manchester but we are therefore able to receive additional armed policing support because of this plan. We are using this to help in our efforts enable the Manchester Games and Manchester 10k to go ahead.

"We are working with event organisers and Manchester City Council to review and enhance our safety and security."
