Lions captain Sam Warburton says the thoughts of the British and Irish Lions are with those affected by Saturday night's terror attack in London.
Three men were shot dead after killing six and injuring 48 more with a van and knife attack in the capital.
The Lions played the first match of their tour in Whangarei on Saturday, beating the New Zealand Provincial Barbarians.
And Warburton said: "The guys have woken up to some news of some unfortunate events that happened in London.
"I just wanted to wish those involved all the best wishes from the Lions players and management.
"Our thoughts are always with the people back home in Britain and Ireland. Our thoughts and deepest sympathies go out to the families and people involved in that incident."
England's football team, who are preparing for games in Scotland and France, expressed their condolences on social media.
"Our thoughts and sympathies are with the victims and their families and friends following the attacks in London on Saturday evening," England tweeted.
Arsenal and Tottenham were among the London clubs to post their sympathies.
"Our thoughts are with all those affected by last night's attack #LondonBridge," Arsenal posted.
Spurs said: "The thoughts of everyone at the club are with all those affected by the tragic events in London last night."
A statement is anticipated on Sunday morning from the International Cricket Council in the wake of the attack and with the Champions Trophy ongoing over the next two weeks.
India take on Pakistan at Edgbaston on Sunday and England's next fixture is against New Zealand in Cardiff on Tuesday.
Before then, Australia and Bangladesh are due to meet at The Oval on Monday.
Australia, set to practise at The Oval on Sunday along with their next Group A opponents, have described themselves as "comfortable" with the security provided - although they will "continue to monitor the situation".
Australia travelled from Birmingham to London after their opening match finished in a rainy no-result against New Zealand two days ago.
A Cricket Australia spokesman said: "As with the rest of the world, the Australian team is shocked and saddened at the events that have occurred in London overnight and our thoughts are with those directly involved and their loved ones.
"The team, support staff and travelling contingent have been accounted for. Our security team is working closely with the ICC and LOC to ensure the safety and security of our players and support staff is paramount.
"At this stage we are comfortable with the level of security being provided to us and will continue to monitor the situation."
Bit of a mixed blessing being among the first out of the traps on a Lions tour: a good start against relatively weak opposition and you're in credit, but it's not a deal-breaker; finish on the wrong side of the ledger and, as in politics, if you're explaining you're losing.
