A suicide bomber went off among fans leaving an Ariana Grande pop concert in Manchester, UK.
At least 59 people were also injured when the blast caused by an improvised explosive device carried by the attacker detonated at the Manchester Arena after the performance on Monday night.
It is the worst terror attack to hit Britain since the July 2005 suicide bomb attacks in central London in which 52 people were killed and came four years to the day Lee Rigby was murdered by Islamist extremists.
Police were called to reports of an explosion at 10.33pm, shortly after Grande, the US singer, had finished her performance as thousands of people streamed out of the Arena.
Greater Manchester Police chief constable Ian Hopkins feared the death toll to rise and confirmed is that there were children among the deceased."
