LONDON — At least 22 people, including children, were killed in an explosion which ripped through a crowd of people leaving an Ariana Grande concert in Manchester, England on Monday night. The identified suspect, 22-year-old Salman Abedi, executed the deadliest attack on British soil since the 2005 London bombings. The attack has left a country in mourning and police searching for answers.
European intelligence said Abedi was a British citizen of Libyan descent. The suspect’s brother has been taken into custody.
Here’s what else we know — and don’t know — so far.

• The blast rocked Manchester Arena at around 10:35 p.m. local time (5:30 p.m. ET) as fans were leaving the venue.

Queen Elizabeth sent a message early Tuesday, via the royal website:
"The whole nation has been shocked by the death and injury in Manchester last night of so many people, adults and children, who had just been enjoying a concert.
I know I speak for everyone in expressing my deepest sympathy to all who have been affected by this dreadful event and especially to the families and friends of those who have died or were injured.
I want to thank all the members of the emergency services, who have responded with such professionalism and care.
And I would like to express my admiration for the way the people of Manchester have responded, with humanity and compassion, to this act of barbarity.
