"It was with great sadness and profound shock that I learnt of the brutal attack that struck Manchester.
It breaks my heart to think that, once again, terrorism has sought to instil fear where there should be joy, to sow division where young people and families should be coming together in celebration.
I would like to convey my deepest sympathies to Prime Minister May and to the British people.
Today we mourn with you. Tomorrow we will work side by side with you to fight back against those who seek to destroy our way of life. They underestimate ours and your resilience – these cowardly attacks will only strengthen our commitment to work together to defeat the perpetrators of such vile acts."
