Europa cup final to continue on schedule

Man Utd's Uefa game in Stockholm to go ahead Uefa has confirmed that tomorrow night's Europa League football final, involving Manchester United, will go ahead as planned in Stockholm despite last night's bomb blast at Manchester Arena.

Heightened security measures are already in place for the event following the recent attack in the Swedish capital. Manchester United, who earlier tweeted their shock and sympathies to the victims and their families, travel there later today. Meanwhile, England Netball, which is due to use the Manchester Arena next month, has temporarily suspended tickets sales for its June 10-11 Vitality Netball Superleague Final Four event at the venue.

A statement read: "Following the tragic events at Manchester Arena last night, England Netball has chosen to temporarily suspend ticket sales for the Final Four. "We will release a further update in due course, for now, our thoughts and condolences are with those in Manchester."

Theresa May on the attack and who attended the COBRA meeting?

Here's more from Mrs May outside Downing Street a few minutes ago: "All acts of terrorism are cowardly attacks on innocent people, but this attack stands out for its appalling, sickening cowardice - deliberately targeting innocent defenceless children and young people who should have been enjoying one of the most memorable nights of their lives. We struggle to comprehend the warped and twisted mind that sees a room packed with young children not as a scene to cherish but as an opportunity for carnage. But we can continue to resolve to thwart such attacks in future - to take on and defeat the ideology that often fuels this violence, and if there turn out to be others responsible for this attack to seek them out and bring them to justice."

Who has attended the Cobra meeting?

Present at the hour-long Cobra meeting were Mrs May, Home Secretary Amber Rudd, Transport Secretary Chris Grayling, Foreign Secretary Boris Johnson, Defence Secretary Sir Michael Fallon and Health Minister Philip Dunne. Manchester Metro Mayor Andy Burnham and Security Minister Ben Wallace joined the meeting by video-link from Manchester.

Also present were representatives of the police, including the UK's most senior counter-terrorism officer, Metropolitan Police Assistant Commissioner Mark Rowley, as well as security agencies and Whitehall officials.
