At least 22 people were killed and more than 59 injured in an explosion at the end of a concert by U.S. singer Ariana Grande in the English city of Manchester on Monday and two U.S. officials said a suicide bomber was suspected.
The blast happened at about 22:35 BST on Monday following a pop concert by the US singer Ariana Grande.
The cause is unknown but Prime Minister Theresa May said her thoughts were with those affected by “what is being treated by the police as an appalling terrorist attack”.
If confirmed, it would be the deadliest militant assault on Britain since four British Muslims killed 52 people in suicide bombings on London’s transport system in July 2005.
Police responded to reports of an explosion shortly after 10:35 pm at the arena, which has a capacity for 21,000 people, and where the U.S. singer had been performing to an audience that included many children.
Unconfirmed reports from two unnamed US officials suggested the attack was carried out by a suicide bomber.
Ariana Grande, 23, later said on Twitter: “broken. from the bottom of my heart, i am so so sorry. i don’t have words.” May, who faces an election in two-and-a-half weeks, said her thoughts were with the victims and their families. She and Jeremy Corbyn, the leader of the opposition Labour Party, agreed to suspend campaigning ahead of the June 8 election.

There was no immediate claim of responsibility, but U.S. officials drew parallels to the coordinated attacks in November 2015 by Islamist militants on the Bataclan concert hall and other sites in Paris, which claimed about 130 lives.
British police were on alert for any further attacks. Central London’s Victoria coach station and roads around it were closed after discovery of a suspect package, the BBC said.
Islamic State supporters took to social media to celebrate the blast and some encouraged similar attacks elsewhere.
Britain is on its second-highest alert level of “severe”, meaning an attack by militants is considered highly likely.
British counter-terrorism police have said they are making on average an arrest every day in connection with suspected terrorism.
