British and Irish Lions skipper Sam Warburton said his side will dedicate the remaining matches of their New Zealand tour to those affected by the London terror attacks.
Three men were shot dead after killing six and injuring 48 more with a van and knife attack in the capital on Saturday.
The British and Irish Lions expressed shock and sympathy for those killed and injured in the attacks.
"We will dedicate to those who have been involved," said Warburton.
"I guess we can play a small part in trying to cheer a majority of the nation up by trying to be successful over here.
"We'll commit our performances and all our efforts to those involved recently in London."
News of the attacks filtered through to the team on Sunday as they were attending an official welcome ceremony in New Zealand a day after they claimed a 13-7 triumph against the New Zealand Provincial Barbarians in Whangarei.
"We've only just heard about the tragedies in London," Lions manager John Spencer told reporters.
"We don't know any detail yet, we just heard about it coming out of the meeting house here. But the boys are very shocked.
"But can I just please express our sympathies with those who have been injured back home. This is a dreadful tragedy and our thoughts and prayers are certainly with those who have been injured – and their families.
"We're four nations but we're one jersey, one team, and we'll all stand united here about the sentiments in London."
