The Lord Mayor of Leeds will lead a minute's silence this morning as a mark of respect for the victims of the London attack.
Coun Jane Dowson will lead the silence at Victoria Gardens in The Headrow at 11am.
A Leeds City Council spokesman said: "As a council and a city we offer our support to the people of London and our thoughts and sympathies are with all those affected both in the UK and abroad."
The flags on Civic Hall and Town Hall will also remain at half-mast until tomorrow morning as a further mark of respect for the victims and their families.
A book of condolence is available at the Portland Crescent entrance to the Civic Hall for those who wish to sign it.
