Manchester Arena blast Britain's deadliest since 2005 London bombings: Here's a chronology of terror attacks in Britain

Nineteen people have been killed in a terrorist attack during a pop concert by US star Ariana Grande in the northwest English city of Manchester, police said Tuesday. British Prime Minister Theresa May condemned the "appalling terrorist attack". "All our thoughts are with the victims and the families of those who have been affected," she said in a statement.

After Irish republicans ended regular bombings in 2001, terror attacks in Britain became more rare. Most attacks since have been carried out by homegrown Islamists, the deadliest remains the July 2005 assault on London transport:
