Gwent Police said they believe the incidents were not terror-related.

Assistant Commissioner Mark Rowley, who leads on counter-terrorism policing nationally, confirmed the US and UK are now sharing information again after "fresh assurances" from across the Atlantic.

He told the BBC: "We greatly value the crucial relationship with our trusted partners around the world so we can collaborate and share sensitive information to defeat terrorism and protect the public at home and abroad.

"While we do not usually comment on information-sharing arrangements with international law enforcement organisations, we want to emphasise that, having received fresh assurances, we are now working closely with our key partners around the world including all those in the 'Five Eyes' intelligence alliance."

The Five Eyes alliance is made up of Britain, the US, Canada, Australia and New Zealand.

"Laura and her friend Eilidh were so looking forward to the concert, but that night has now ended in a tragedy where Eilidh has lost her life and Laura is in a critical condition," they said.

"Our hearts and minds have been with Eilidh's family since we heard their news.

"We know that Laura is in the best possible place and is receiving the best care that she can. Laura is strong-willed and a fighter."

But now a decision has been taken to end the temporary suspension after assurances were received by counter-terrorism officers in the UK.

We've learned over the last couple of days that the Manchester killer had been on the security services' radar, but what was specifically known about him isn't quite clear, other than he wasn't a priority for investigation.

So how does MI5 make these incredibly challenging judgement calls over who to watch and who to put to one side?

It has to priortise - putting attack-planners at the top of the list and the hangers-on at the bottom.

My blog this evening looks at how bewilderingly difficult these decisions are - and where Salman Abedi may have fitted into the bigger scheme of priorities.

Former US President Barack Obama believes the perpetrators of Monday's attack will be brought to justice. Here's what he said:

"I know this not only because of the confidence I have in our military and our intelligence services and our law enforcement - but mostly importantly because I know the character of our peoples.

"And you can see it in the way that the people of Manchester responded - not simply with fear but resolve and with kindness and solidarity and a willingness to help people who are in need.

"That's why I believe we will prevail because our way of life is stronger."
