"Wakefield stands in solidarity with Manchester. If this is confirmed to be a terrorist attack we will not allow them to win."
In a joint statement Bradford Council leader Susan Hinchcliffe, chief executive, Kersten England and lord mayor Abid Hussain said: "Our thoughts and prayers are with all those affected by last night's terrible incident at Manchester Arena, which is believed to be a terrorist attack. We are aware that a number of people from our district are among the injured and we wish them a swift and full recovery.
"The Union Flag on City Hall has been lowered as a mark of respect, in line with all government buildings across the country.

Leeds City Council leader Judith Blake said: “On behalf of Leeds City Council and the city of Leeds I want to express our heartfelt sympathy and support for the people of Manchester. Manchester is a great Northern city with a rich heritage where people of all cultures and creeds live together successfully - values Leeds holds in common.
“The deliberate targeting of children, young people and concert goers in this way is beyond comprehension. I know many people from Leeds will have family and friends who were in Manchester last night and I would urge them to use the contact number provided by Greater Manchester Police if they are still concerned about their loved ones.
“As a council and a city, Leeds stands ready to provide whatever support we can to Manchester at this unbearably difficult time."
